Site redesign for X-Cart store

Looking for a redesign of our store into something much more clean, modern, and SEO friendly. Site design should be along the lines of the simplicity and functionality of c s n stores, walmart, target, etc. with minimal need for images in the interface. Our current design can be used as a point of reference (msg for web address) but you will be working with a default installation of X-Cart 4.4 Pro. Most of the work will be on the home page, header and footer. Category and product pages will need little adjustment except to fit in with the design upgrade. Requirements: Must utilize easily customizable jQuery-style plugins for functional elements. Product carousel for new/featured product presentation on home page and on category pages. Category display boxes laid out similar to csn store. Prominent display of search box at top of page. Graphical elements must be clean and should use CSS positioning to save on HTTP calls where possible. Template changes should be SEO optimized.
