cakePHP (agriya groupdeal) Expert Needed

We've got the Agriya GroupDeal script which is based on cakePHP. We need an expert in this specific software, someone who has worked on it multiple times. We want to add categories such as: Getaways, Mobile, Jewelry, Home, Kids. Each category should have its own daily deal and related side deals. The back end will need to be modified as well to accommodate this and also instead of creating a voucher, it needs to store the purchases just like a shopping cart. The automated emails need to also be changed. Overall I need this integrated and working smoothly in all aspects. Example of sites with categories: [login to view URL] [login to view URL] [login to view URL] Keep in mind that I still want to have the daily deal category for local/online/offline plus up to 5 other categories. Again, only looking for this EXPERTS in this particular script and PHP. Only programmers with proven record will be accepted. Looking for top notch work. Thank you!
