198253 PHP Site Development.

I have a website that is rougly 80% finished. I had hired a web developer, and haven't heard back from him for 3 weeks, after paying him in full. So I didn't get a finished project. I have all of the files, that he developed, and can provide. The site links service providers with service seekers. Industry specific, and can share this once the project has a developer. PHP, MYSQL, Concept. People seeking the service can log in as user type A (non paying). They can post their request/need, then User type B, the service provider can log in (as a paying member) using paypal subscription payment method. And they can bid, on the User A, request. The bids, remain private, and communication between them and User A, remains private within the system. More details when chosen freelancer/developer. Also, will require signing of an NDA.
