Complete Webshop Rebuild with Joomla Virtuecart

We need a complete redesign + reprogramming of our current HTML version website. We want a special webshop based on joomla with a special design and some added modules....our current html website [login to view URL] The speciality of the webshop would be that when a customer has selected a sofa he could then choose a special color to it. Then he could see a preview of the sofa with his selected color and if he likes it then he would "order" it. But instead of ordering we would give him a special coupon that he could print out and take with him into our showroom. This way he could get a discount... Main Task: - Creation of a cms based special webshop with unique design (e.g. by using joomla virtuecart modul!) - installing and modifying special joomla extension modules based on our own requirements... - possoble programming of brand new joomla modules if they are not yet existent - creation of a complete product showcase and showroom inside our joomla webshop (integration with our current flash version of product showroom) Main Functions we need: - product listing feature (similar style and way as on this website:[login to view URL]) - detailed product description of a given item (see - [login to view URL]) - rating + sort by rating (as seen on here:[login to view URL]) - sort by price (as the left side menu here :[login to view URL]) - product search by name - hotline nr with hot girl on the top right always - "you can save"....in USD and also in Percentage amount( %) (as seen here: [login to view URL]) - zoom in function to enlarge product photos (e.g.: [login to view URL];CategoryID=35882) - color selector, and see the results (e.g. as seen here [login to view URL];CategoryID=35882) - what products are currently on stock....as a listing option also - Items on Sale - auction modul - the future possibility to expand as a "normal" online shop....whereas right now we only need a coupon to be genarated (with customer name, product data, etc...) that can be printed out by our customer....valid until....
