Website Design & HTML5 - ecommerce

Our goal is to develop a new design based upon the the Gruopon business model. I am looking for a fresh design not a clone of groupon or other group buying sites. I have ideas that I can share with you on the look and features of the website. I am looking for the design (Photoshop) and HTML5 code developed but not the back end database code (I have a developer on our team working on that part). Must have prior experience with developing ecommerce websites, groupon style or aggregators is a plus. I don't want to start from a template and must have clean HTML5 code. I don't not want to use Flash but may have some flash like features.
