Database Linked Ecommerce Website

Brief to design an ecommerce website which is highly tuned for search engines (metas, header 1s, 2s, link authority, site structure etc) primarily Google. Something similar to [login to view URL] which produces excellent search engine results. SEO needs to be at generic product description/category level (i.e. "Audio Visual" and "projector stands" and "video projectors") and specific product level (e.g "Hitachi CP-X1250" and "Sony CCP-1310F" etc). Please provide samples of sites where you have been able to achieve this. On the database side, the site will require to be uploaded on a daily basis with a CSV feed from our stock file which will include fields such as... - Product Title (e.g. Hitachi CP-X1250 Video Projector) - Product description - Product picture source file location - Product Price - Stock level (units held in stock - 1,15, 20 etc) The site will then need to be able to process transactions fully online via a shopping cart facility, and process credit card details online via SECpay, Worldpay or an equivalent. Design and funcitonality of the site should be something similar to [login to view URL] It is highly unlikely that a generic opensource shopping cart such as zencart or oscommerce would be suitable for this application - although if you can demonstrate instances where you have achieved this we shall consider it on its merit.
