Costum shopmodule, build on Joomla 1.5 and Virtuemart 1.1.4

Hi, I need a costum module in a webshop, build on "Joomla 1.5" and "Virtuemart 1.1.4" EXACTLY like this: [login to view URL] (The example is a danish website, but still easy to understand) Description of functions: A: 3 collums: Left: The Product groups. Middle: The Products. Right: The basket. Please note: The Product groups and the basket follows up/down the screen, ass the costumers scroll up/down. B: In the middle box, every product must have a small thumbnail-picture in the left side of the product-description, and the costumers can make a mouse-over the small picture, to se a popup larger picture of the product (Ajax?). C: When a costumer click on a product [+] then 2 things happend: 1: A text "I kurv: 1" appers in the product itself, and counting up if several clicks are made, all in realtime. 2: In the right collum, the product is been added, and counting up if several clicks are made, also in realtime. D: In the right collum, every product have a small pencil-icon, the costumer can click on. If clicked on, the product-basket expands, and the costumer can adjust the numbers of the specific product (more or less numbers of products), or remove the product. If all the products are removed in the basket, a default text appears, telling the basket is emty. E: The basket is automaticly counting the prices for each type of product, in the basket (in DKK). The basket is also automaticly counting the totalt prices for the product, in the basket (in DKK). And the costumers can only buy the orders, if the price reaches a minimum price (in this case 250 DKK). Only then, a order button apears to proceed the order. Note 1: The programming must be in such a way, that your work comes as a extention (XML), ready to install into Joomla. Note 2: The example-website is in danish, but the programming must be in such a way, that the language is adjustable via the Joomla Joomfish component (for danish, english, sweedish and more languages) Note 3: The programming must be in such a way, that I can update Virtuemart from time to time, without destroying anything of your programming, and with no problems or conflicts. Description of design: I only want a simple design (just like in the real-live example), where all colours, bg-colours, fonts, sizes, and so on, is possible to edit in a CSS-document (with-easy-to-find-code through comments). Terms: As soon as posible! The payment methods to you is in cash, through our banks. All copyright belongs to my company. Thanks: FLJE (Consultant for Guru Takeaway)
