Hey John, some advice you probably know but I'll say it anyway: You're gonna have to increase those salary ranges. Almost everyone in my NYC college graduating class who got into programming got a job that paid at least $65-70k, with no experience. Those with more experience got up to $90-100k. And of course, you want someone experienced to build your product.

Just saying in case you're having trouble finding people local in NYC.

Aside from that, the project looks super interesting. Best of luck!
