PHP / MySQL Expert Required - Fix PHP Errors - Custom Site

After having issues with our server for the past few days, we have switched the php module we use from suPHP to DSO. Doing this has broken some of the sites permissions and php functions. Most of them I believe are related to chmod & related permissions, however we can not seem to rectify them, so require someone more experienced to help us correct the issues. We also have a few unknown php errors related to sessions that we can not seem to find the source of. This is a very simple job for someone who has experience in both PHP & MySQL. Example of Errors: Warning: unlink(include/[login to view URL]) [[login to view URL]]: Permission denied in /home/xxxxxxx/public_html/[login to view URL] on line 9 Fatal error: Maximum execution time of 60 seconds exceeded in /home/xxxxxxx/public_html/[login to view URL] on line 12 [Sun Jan 09 16:28:28 2011] [error] [client [login to view URL]] PHP Warning: Cannot modify header information - headers already sent in Unknown on line 0, referer: [login to view URL] NOTES: You must be available to start today. Skill Set Required: -PHP -MySQL -Ajax -Javascript +MySQL Optimisation / Slow Queries. We also require someone for our next project to Optimise MySQL & Slow Queries on the site, this will involve replacing code for more effeciant code that will lower the amount of queries used and improve any slow queries the site has. Important: When bidding, please give an overview of your skill set, your previous experience related to this task and how you plan on tackling the job. (e.g. sell yourself) I am not impressed with responses like: "I can do this"
