Implement PHP Code onto Server

We have a web application already finished by another coder. Due to a dispute, we want a 3rd party to implement the code onto our site. We are using a shared linux server on GoDaddy. The program was written in PHP. Original project can be found at Bid ID 1292763 This is a fairly simple and quick task for an experienced person. I have attached a copy of the final code. Also, please make sure that both the code and the server are clean (no viruses) before installing code. If there is any malicious code residing on server, please help to remove. If it is a difficult task, we can negotiate a better fee. I have ask another admin to check and they say that server is fine. **12' I763**
