PHP Code tester

I have had some PHP file code developed by a freelancer on this site. The code was for a simple web based game. I now need someone with access to their own web server to test the code and tell me if it meets the requirements of the original spec. I wish to know exactly how the code functions and what it does so a full diagnosis is required so please only apply if you are comfortable reading code and understand full how it works. I cannot read the files myself and it may well be complete nonsense and not firt for purpose so I need someone to help me. The testing is just the first phase of several and I would like to hire the same freelancer throughout the process so please only bid if you are available for continuing work. The next stage would involve integrating the code into a web page so I can beta test. Please only apply if you have significant experience in PHP and the time to work on this. Please note I will not be releasing money upfront - I am happy to load 100% money in as a milestone before you start but I will not be releasing any part of it until the work is completed. I also want a freelancer who can communicate progress, please be realistic on your deadlines, I have had instances on here in the past where freelancers have gone way beyond deadline and not informed me that this would be the case. I therefore wish to only work with mature professionals.
