BUG HUNT - PHP CMS Bug Fixes - Current Site Needs Bugs Removed

We are currently using an Opensource CMS written in PHP and it uses MYSQL 4. The problem is the source is still buggy and we dont have time to wait for the development team to fix all the current bugs. So we are looking for a compitent and capable person or persons to step in and fix the list of current issues and possibly extend the source to our own requirements. If the work is completed satisfactorily then there is opportunities for further contracts of work. Applicants must be able to provide a portfolio of recent and past work. It would also be beneficial for applicants to be familiar with media player plugins such as Quicktime and Media Player as well as javascript as this will be required for future work. We would prefer to deal with the same person or persons throughout all ammendments to the source. Most of the work will be with the php source rather than the Database but MYSQL database experience will be needed. Further details to be discussed with the applicant.
