Just to be clear, I'm not in dire straits or in need of a million dollars. I'm just curious.
Additional clarification: For this purpose I'd like to assume someone doesn't have a million dollars or the prospect of receiving such in a lump sum. How would they go about building up to a cash flow that would be equivalent to having a million dollars in a safe, hands-off investment?
edit: Apparently I don't know the difference between conscious and conscience. Fixed.
Any suggestions for such an app that people here would find useful and willing to pay, say, $10 a month for, that would be small enough to be developed by one guy? I can't think of any ideas off the top of my head.
Seriously?!
So you work in a company? Do they use Excel to track some kind of business critical process? There's your $10/month business...

Poster above says "to do lists" and I agree enough that a To Do list was #1 on my "list of software product ideas" before I started the current one.
What's wrong with RememberTheMilk? Once you figure that out you'll know what to build!
edit: they are one of the HackFwd startups
So, I agree that a niche software product you're actually passionate about will help. I happened to be in a fortunate position where a demand existed for a one-off product I had created a while back, all I had to do was fill the void. Customers were already looking to me for it. I feel like a total fucking idiot for not doing it sooner. I could have made probably 3x the money, just guestimating. Find something that inspires you personally, because that is what will push you to completing it.
I got laid off from a startup position that was caving in. I had a small severance to live off of, and had always wanted to build this idea. Unfortunately while at the startup I was also working on a second one on the side (death, I know) so I never really had time to do anything but those two things. Getting laid off was perfect. I sprinted as hard as I possibly could for 3 weeks, designing, coding, and building a sale site with a mini activation server. It was loads of fun. It was also very exciting to look back on those three weeks and realize that I had done a great job making the right decision when hit with a small road block. Asking myself things like, "Where does this fit with the 80/20 rule? Can I launch this feature in a second update a week later? Do I need it at all? Oh, wait, these two features can easily be combined into one. The technology behind the two won't be nearly as cool, but users will probably prefer it." All of that, I feel, is what lead to my success. Getting the product out as soon as possible, without cutting any essential corners. We've all heard it before, but living it was great. I guess I pretty much built my own "nano" startup.
Damnit, now I want to do it again.
This happened to me today and I totally understand why people want to go the startup route. Ever hour invested into your startup is an hour that gets you closer to where you want to be.
A couple of "route finder" reviews posts on an old personal blog of mine suddenly did well on Google and, as was the trend, I had Adsense on my site. Just from those few posts, I earned between $2000-$5000 most months of that year (with one stray month just shy of $10000) and did little "real" work that year. In 2009, Google penalized the blog because I got greedy and started running "text link ads" on the front page (dumb idea). Traffic crashed and the income stream disappeared.
I eventually got the penalty lifted but by then a lot of people had figured out that ranking highly for the names of the top route finders was a goldmine and now my posts are on page 2 rather than in the top 5 results and make rather little.
Interesting while it lasted but the work I'm doing now to produce an income feels more rewarding than checking Adsense 20 times a day ;-)
Original price was $29, and there was a Premium variant for $49. Eventually the source that was pushing so many customers to my site stopped using the theme herself, and my traffic/sales died substantially. I figured, "It had a good run, time to move on) so lowered the price to capture more of the trailing edge.
If it brings at least $100 a month, I'll work on nine more sites like that to make a grand.
Ad revenue. Mailinator claims they get a million emails a day, that's a lot of money in ad revenue. My goal is to dethrone mailinator as the de facto temp email provider.
All built using AppEngine, python, webapp and notepad2.
It leaves out a large part of the problem of selling something. How will enough interested people discover the "simple web app"? If there are competitors (chances are there will be) and the app's page is in the 12th results page of Google and PPC keywords cost $5 per click, getting enough relevant traffic to ultimately reach 400 subscribers can be quite a lot of hard (and costly) work.
As an indication, if you look at point 5 in this survey http://webappsurvey2009.techcrunch.com/ you will see that ~50% of marketing sites of web apps got 0-1,000 visitors a month.
It can be done but don't just expect to "build it and they will come."
Also, a book that sums up good points about selling a web app (especially if you are a developer) is http://www.startupbook.net/
Good luck!
But if it's just a simple web app, presumably one that has some similar competition, then $5 may be a better idea.
I recently asked a question about this: http://news.ycombinator.com/item?id=2000924
HN gave me a lot of great insight to Flippa
Really you need to leverage some kind of skills to go after something either outside the low hanging fruit, or create something that people wouldn't have considered to have a good enough market. Of course there is an element of luck, if you can make some apps and get them to take off, the mobile ad market seems to be like the early web advertising at the moment, probably returning above the mark. Something like this for example: http://news.ycombinator.com/item?id=1870960
A short list of items that meet this qualification: software, writing (books, novellas, blogs, etc.), digital art, digital photography, music (original), sound of other types (background sounds that can be used in the production of music, for example), designs/instructions (for building something) and a probably a bunch of other stuff. If I missed a big one, please reply to this post with it. You should also be looking for free resources online that you can leverage. Are there free services that you can leverage to make your business easier to manage? Can you do some work (collection or processing) of some freely available data that might give it additional value which you can then extract through sales or in some other way?
Because your goal is to make a living and give yourself some extra freedom, you don't have to overengineer this. This isn't your masterpiece. It doesn't have to be pretty or break new ground necessarily. Don't chrome plate it if you're writing software for it or to support it.
Frankly, I just started taking advantage of this type of business and I feel almost guilty. The code isn't that great. The idea isn't that great. It's not something to write home about in terms of engineering a solution. But it makes me money even if I don't touch it for a month at a time. I'm not living off this business yet, but I am seeing good growth and I see a virtually infinite path to expanding the digitally based offerings of the business (more offerings = more money).
One option during this down market is to purchase rental property, you'll have to do some digging but the most depressed markets are 70% off of their peaks and most pros will tell you it won't drop much more than that (but it's not ZERO risk). You need to crunch the numbers and then renovate and find tenants but I know of a few small investors that own 15-20 rental properties and can generate ~10% margins monthly and you have the potential upside of property appreciation.
If you don't want to deal too much with getting hands on and managing a business, it's conceivable to be pretty low-risk to go with high dividend / low growth blue chip stocks. For example, AT&T is at $29/share right now. It's been paying $.42/share per quarter so about $1.60/year. It'll move around a bit but assume that they won't get screwed when the iPhone goes multi-carrier, you are talking about $1M for 34,483 shares which will pay $13,793/quarter in dividends alone which is $4,597 per month. Assume 40% taxation rate and you're $2,758 post taxes. You can use any finance site to screen for companies with high dividend yields. Keep in mind that high dividend usually means low risk of stock price movement but there is still risk.
I've done side/hobby projects of both the ad-driven and subscription-driven flavors, and the subscription-driven stuff gets a lot more profitable a lot faster. It does incur additional stress, because you have direct paying customers to take care of, but depending on the nature of the product, it might not need that much support. On the flip side, it's friggin' amazing to watch payments come in on a daily basis, then look back in a week and realize that you've got your rent paid for.
