I copied this info from our bootstrapped startup annual report. This info covers development and first month revenues.
Money and hours spent:
10$ + 2 days - domain+naming
9$/m - hosting
0$ - 1 week - webdesign (~ 3000$ value)
0$ - 1 day - front-end development (~ 300$ value)
0$ - 1 week - development (~ 1500$ value)
0$ - 6 days - copy writing (~ 500$ value)
- Facebook official page created 05.05.2011
- Money and hours spent on advertising : ~ 200 $ + 1 month work (~ 4000$ value)
- Over 800 emails received and replied
- 12 paying costumers. (450x12=5400 euro)
- 3 refund (250x3=750 euro)
- Profit - 4650 euro
P.S. Actually I should spend 10000$ for the launch, but because I did everything myself, I didn't spend so much money. I spent too much time learning graphic design, marketing, seo and my expertise on my startup subject. And some coding skills. But because all of them were already familiar to me as a hobby, I dont't count the time spent on learning developing my startup.
