I'd agree, but argue that at the same time, you'd want visit in person anyway, so its meaningless from both sides of the market. I had to give up on this idea, so I may be biased. Some people are making money, and there are actually some really cool ones out now with "true" 3d modelling, but I don't think its worth pursuing. You'd be better of with something your customers actually want to pay for. (sry if negative on this)

BTW, since you appear to be bootstraping, you should check out barnacl.es, it's a community for like-minded solo startups doing their own thing. PS: for some reason I can see the wordpress header bar on your website now, some sort of web cache artifact or something?
