Profesional Web Design (FOR GATO ONLY)

This is a re-post of a project for service provider "Gato". I need a professional web design made. The content will be almost the same as [login to view URL], but the name of the site will be a different. I want creative ideas on navigation and vehicle / sparepart connections so it's very easy to find parts that fit the vehicle. MotorSweden have done it with tags, but I don't think it's the best presentation of it. What I need is all pages a webshop have with easy access to cart and webshop features 1. Start page with navigation, one navigation for vehicles (around 3-4 categories) and one navigation for spareparts (40-50 categories). 2. Product listing, maybe a different product listing for vehicles vs [login to view URL] pictures and more information for the vehicles maybe? BE CREATIVE! 3. Product information with add to cart buttons and other good features. Support for many pictures, I will probably use a lightbox. 4. Cart that shows the content of the cart with pictures on the products in the listing Think very much Web 2.0 - please use jquery for some cool features! Input on good social network integration is welcome! Maybe some twitter rss on the page and such? Make the visualisation of as much features as you want - we will create the dynamic parts of it later, we use a self developed webshop platform that we can build to fit the design. The sites name will be "keepout", so it should be a cool design with "Keep out - private property" in mind, it should look cool to people around 18 but not look childish, so older people will think the site looks serious and buy products for their childrens.
