PHP fix and clean - repost

Hi, My hosting server was recently upgraded to a new PHP version (5.0 to 5.3) and my website has become incompatible with the upgrade. I would like to hire a person that is experienced with coding and PHP to help me fix the issue. The script I have has been heavily modified and the authorization for license removed. DO NOT WORRY, I paid the original creator of the script a premium price to have full rights to the script on my site. My site is [login to view URL] and have been online for almost 5 years now, so you could see that my site/script is perfectly legal. I will provide a copy of the script (a modified version) for you to compare codes. Unfortunately my script creator disappeared and the new owner of the script is not responding to my emails. I downloaded a copy of the script ONLY for you to compare codes. Please remember, this is perfectly LEGAL because I paid a premium. In no way am I using an illegal version of the script or asking you (the programmer) to act in any blackhat methods. Please remember that before bidding. Secondly, I would like the person to update/clean all my website coding and files as it has not been touched for a few years now. I last had it checked 2+ years ago, but would like to have it checked again. All unnecessary files may be deleted. Lastly, I have both the facebook and twitter api on the site, but the facebook needs to be updated to "https" and twitter needs code updated. The codes are already written, so only need small modifications. I am not going to be able to pay a lot as my budget is low. If you are a new programmer here on Freelancer, this may be a job for you. As long as you have a few feedbacks, I'll hire you to help you build up your portfolio. Budget: $30-70 - I will pay more if I require more things to be completed, but simple tasks. *Besides modifying the PHP code to work, everything is simple, hence why I place a low budget.
