Build Amazon storefront style website

We are looking to build an Amazon storefront style website and need your help. Background: the website will offer an easy and interactive interface that will allow an efficient way to find “the perfect gift” based on just a few questions (filter based). Interface: we are looking for something easy and friendly, similar to [login to view URL] , [login to view URL], etc. Filtering: we should be able to add/remove filters and categories and select the number of the ones presented on the main page. The filters will be multiple choice - style. Categories: we need the ability to add unlimited number of categories and sub-categories. Every product can be linked to a number of categories and sub-categories. Adding products and links: we need to have an easy and efficient way to upload masses of links with the ability to see picture and description prior to uploading to our website. Social Networking oriented and Google friendly Mobile device friendly Visual: similar to gogifts.com- the filters will be located on the top upper third of the website and the products presented under will change instantly based on the filters. High level graphic design is extremely important Thanks! GiftHunch Team!
