Retired, my home is what amounts to a small castle (ex-church), multiple vehicles, 200" home theater, no mortgage, no loans, investments a-plenty, two wholly owned, profitable businesses that run themselves, and the software that put me here now available for free to anyone...
Okay. Good for you? What does that have to do with the silly point you were making?
Moving on to something relevant:
$7k isn't exactly a big return over a period as short as two-months. Even $47k over a year isn't great working for yourself, by yourself, in most places. It could be okay if you live in an area with a low cost-of-living, you were single, worked out of your home, and didn't need health insurance.
If you hire anyone, expect that 7k to vanish in short order. Even at $47k, you'd be lucky to pay a second developer for more than a few months, even at a very low rate.
The point? The "hidden assumption" that development takes a year is nonsense.
