Dating Site partially finished need completion

I need a fully functionable and scalable dating site that is geared to a very specific audience. I want to incorporate the best features of the major dating sites. I had hired a developer for the job but had to fire him. I am hoping some of his code is usable. It appears the backend he created is almost complete. The frontend is quite primitive. It would be nice to have someone who has dealt with this kind of project before. I have a vision for the completed site but would welcome suggestions on functionality. As per the graphics and layout I would gladly defer to someone with more experience in doing these kind of projects. The first thing I need is for someone to look at his code (I have it hosted and I have the doman name). Then I need someone to finish the job. I am not the most computer savvy person. I need a programmer that will communicate clearly with me and be a team player throughout the whole testing and implementation process. There are some segments that were never completed such as a zip code distance calculator and a software to keep track of customer information. Depending on the costs involved I may farm out the frontend aspect as a separate project. I am hoping to get this all done for under $500. However we can round that figure up if it seems the previous code is quite incomplete. I'm not sure if I am going about this properly. Perhaps checking the code is a separate project in itself. If anyone has suggestions on how to both have the code checked and have someone finish the job do let me know. I am somewhat new at this. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Installation package that will install the software (in ready-to-run condition) on the platform(s) specified in this bid request. 3) Complete ownership and distribution copyrights to all work purchased. 4) Developer will work in concert to test and make adjustments to the software as is necessary before fully launching the site. 5) Will negotiate the terms of staying part of my team in case upgrades and changes to the site are necessary. ## Platform The code I have is already hosted on a Linux Server. I believe the site is written in PHP with a MySQL database.
