Product Information Website

I am looking at getting a product infomation site created. The site must have a CMS engine that allows me to add product, descriptions, specifcations, pdf's, graphics etc. Multiple pdf's and graphics per product Products must be able to displayed by category, manufacturer, industry, by drop down search bars, Require tabbed screens and tabs within screens eg each product will have a specication screen, a Product Description Tab, Specifications tab, images tab, downloads tab, video tab, related products tab. Main page should have product tab, category tab, support tab, resourse tab, plus normal contcat us, where to buy , privacy policy etc The site will be loaded with about 5 manufacturers products totalling about 2000 products. every product has a unique Skew, plus a unique manufacturers part number, and name. Site should be optimised for search engines, and content indexing. images and pdf's will contain linked to unique skew, eg part number FX136a image will be [login to view URL], [login to view URL] etc, pdf will be [login to view URL], [login to view URL], [login to view URL] etc, the "-"in the file name can be any chosen character but will be consistant throughout the site. The site should automatically create thumbnail images of loaded images for quick display and when selected should show the full image. Company logo's and graphics need to be able to be loaded simply by loading the required graohic into a directory on the site, likewise manufacturers logos and banners should be able to be displayed through a rolling banner that randomly selects banner images from a preset directory. Website can be pho windows based or Liniux based database MSQL or mySQL depending on platform.
