Zend Optimizer Expert needed

Several months ago we started a project via Freelancer and chose a developer that promised great results but never delivered. The project is 99% completed and needs to add one field to the xml feed in Zend Optimizer. Before you bid send me a PM so that I can release the URL to you. What needs to be done is a 10 digit unique affiliate ID added which should be generated randomly but can only be used once. Happy Bidding. As we are not familiar with Zend Optimizer, the winning bidder has a good chance to weekly work on the application as we plan a lot of changes to the application. Happy bidding and do request the URL before you start the bidding.
