Basic B2B eCommerce website

This project is a basic B2B eCommerce site/shop - the customers will each get a login. When they enter the shop, the shop must recognize the particular customer, and when an order is placed, an email with the customer information is sent. The products are maintained from within the shop admin, with a single form for entering the product data(product number, description, and so on) and choosing a picture from a gallery (preferably with a function like ImageMagick) It must be possible to see all products with a small thumbnail. It must be possible to see a grouped list (imagine fx. 10 groups with X number of products) It must be possible to see the single product in detail. It must be possible to search through the products with a product number... and maybe also free text. Adding to basket must be possible on all product list levels... with a # of items, and a calculation of the individual prices and a total. A new products listing would be nice.. The admin and the frontend should be possible to change into different languages with ease. The design should preferably be CSS controlled. This is B2B so it must be easy to order with a few click of the mouse. The possibility to reuse and reconfigure the shop for other purposes will be very important. We are looking for a lasting relationship with a skilled programmer, with experience from several succesful OpenSource eCommerce solutions. Thanx NDD nordic design
