Cake/JQuery/Mysql - hardcore very experienced only

A project we have been working on has stalled - our developer overcomplicated the database and threw up his hands. This needs thought and attention. The database rebuilds itself post-editing, inserts nodes into cache and is quite sophisticated. In addition, there are many small features which need to be build: image rotate, video display, cms integration, and admin needs quite a bit of work. The JS is Jqeury. The PHP framework is Cake. We will check your references before any passwords are provided. Be prepared for this before you bid. Expect this project to take 1 month but to include ongoing projects in the future.
