Niche Dating Website in Virginia

While cycling on the Washington and Old Dominion trail, I noticed there were a lot of attractive, fit, and friendly people out there. It came to me. There should be a way for these people to meet up and date. They all have at least one great thing in common, and it's a niche that is currently unoccupied by anyone. I want to build a dating app geared toward the thousands of users of the trail, but I need help to design a phone app. That's where you come in! I need about $4000.00 to create an app and advertise.

I'm starting a small business in which I originally intended to provide B2B IT support. But why limit myself? I will include app design for phones if I come up with viable ideas and can raise funding.

Can you help? In exchange for your donation, you and up to five friends get free unlimited access to the app.
