Have you validated your idea by asking your peers if they would be willing to pay for your service?
This would be my first step before committing several thousands of dollars to an idea.
Hack together an MVP, share it, iterate iterate iterate, who knows ...
I'm curious, what is your take and how does it differ from everyone else?
What is your e-mail? Let's chat.
You shove it up your.. heh. no.
Start with trying the idea. If you can't implement it in whole, implement it in smaller scale first.
I believe 7k is good enough money to put together a MVP if you know little bit of programming. Or talk to a programmer and convince him to work on this project on a 50% partnership along with 5k monetary compensation. I believe if you contact few programmers and clearly express your idea and where will it go in long term then somebody is going to help you. At least to build a MVP which you can test to see if it has any potential to go anywhere.
