PHP coder with ZEND experience required for project - repost

I require a coder with ZEND experience to work on my new project to convert an existing social engine site from version 3.20 into the latest 4.60 ZEND version of the same script. All files from my existing site will be required to be converted into a ZEND structured file and new features to be added during the project. Please only bid if you understand the project and not just copy and past a portfolio of previous work, I'm not interested unless it is Social engine work.
