new web interface for ecommerce site

Looking for a graphical redesign of our ecommerce site. Our site currently has one major category (software). We will be incorporating 2 more major categories (1 - Software licensing ; 2 - Hardware). Main focus of redesign will be the 'menu' to incorporate the new categories. Submissions must include mockup of new interface. Designer will need to also develop/program the redesigned site using CRELoaded (mandatory)
