Build a Website -- 2

I would like an ecommerce store redesign. My concept is similar to the implementation of auction sites similar to ebay. The main menu would follow the format of large icon of different sizes similar to pinterest: Auction, Buy, Sell, Seach, Help, Catagory, Community, Blog, Stores. When each main menu is clicked a page appears on the main menu however when the catagory is clicked the page is navigated to that category or item etc. The background must be white. The top page should have a sign in button that does not change during the page scrolling. The home page should comprise of featured items showing big and bold next popular items recently added then popular items. the top right hand corner should have a sign in which should remain on top the page no matter what part of the page is scroll down. There should be a separator which shows the items such as policy help etc. For the main category there should be like a photo pins like pinterest showing the featured listing for each sub category this should navigate the auctions listing for the main category. There should be no external links allowed. I do have the back bone for the website sites separately but it needs to be fused together to create an original auction site which do require programming. The back office should have [login to view URL] similar. The foum [login to view URL] Blog to allow each user to post their blog about the items. Contain the affiliate page. The page should follow the format similar of pinterest.
