If you don't have any other streams of income, you might want to think about ways you could get $1k/mo flowing into your bank account to keep you afloat while you flesh this out. $1500 isn't a lot of money, but perhaps that constraint will just make you more creative.

As for the validation that you're seeking, I've seen people do much crazier things that have turned out well. Which is all to say that, yes, the idea is crazy -- maybe even just crazy enough to work if you are committed to it. It sounds like the downside risk to you is pretty minimal, so why not?

To get you started, here's your first tip from an entrepreneur: don't be too attached to the outcome you have planned now. Just like in a startup, once you start on your adventure, you may find that going in a different direction looks more promising. Take the first step, then go where opportunity leads you.
