Create a simple niche freelancing and job marketplace iPhone appl

I have designs already. I will provide you with the designs. I need an iphone application developed for a niche freelancing site where employers can create projects and freelancers will bid and complete projects. The app should be light and simple. Features of app includes 1. User registration. 2. Same account for employer and freelancer 3. Post project 4. Project search 5. Members chat. Chat allows video chat. 6. Bitcoin payment. 7. Users can give and receive feedback. Project is urgent and freelancers who can complete this project in 3 to 5 days should apply
