Hi,
I have gone through the complete word document you have sent along with the bid. I have a complete dating project written with me in c# and ASP.NET in MVC framework. I have been working on this project for last 2 months. But, my previous client has stopped the project in between. I can give you the demonstration of it.
I have implemented all the important feature you have listed - the location-wise search through Facebook is implemented. The Google API is implemented, paypal, credit card, video chat through WebRTC, virtual gift, wink, search, advance search etc.
It has most of the features you needed. You can either continue me to develop it further or you may ask any other developer to carry forward the project.
We may further discuss on this,
regards,
Nittile
