Bug Fixing/Feature Implementation Thrillz

Hi, I have had my site designed and it is now online > [login to view URL] What brings me here is there are a few bugs, and features I want to add to the site, including fixing links, fixing some bugs in the gallery system, add invision forum software to the site instead of the mingle software being used at the moment. The website is completely built in wordpress so people wanting to get on this project would have to have a good knowledge of wordpress.
