Hope this is not against the board rules (seeing as how I'm new here) but you should check into Fiverr howelzy.  They may have someone willing to develop something for you for much more cheaply than you might expect.

In my highly uninformed opinion, I base Bitcoin's value on its potential.  If indeed we can capture a significant market share (even just 1% of the GDP for the world) we would easily be looking at $50K-$100K per bitcoin in the next 5-10 years.  Just an opinion though, so take it with a grain of salt.
