Oh yeah, there are people who offer the same old boring stuff, eg. make me a Bitcoin converter.
I'm talking about something unique, something different, otherwise there is no point.
Although, if you want to run this sort of business, you need to learn for a long time, it does eventually pay off.
The point? The point is that there are a ton of programmers and "programmers" offering their services. Basic supply and demand states that OP should try and start something that isn't a programmer offering their services, since there's already a huge supply on that front.
Unless, of course, there's some kind of creative angle to be had by applying programming skills.
I'm actually having a fuckload of a hard time finding anyone with any skill in node.js.
