Website for wholesale products

I am looking for a web designer / developer to create a simple website with a CMS system to update products in the backend. I am not fussed which technologies are used, as long as the price is reasonable and it is easy to update the product information. It is for wholesale bicycles. The home page will be a list of products which can be filtered by price, wheel size and other options, which the customer can modify, plus a search functionality (AJAX for immediate updates). Each product will have attributes such as wheel size, frame material, number of gears, colours, price, images, description, model number, stock etc. Users can click on the model and see more information on that product. They can also choose to buy wholesale, for which there will be different price structures set up depending on how many they buy (e.g. x1 is more expensive per bike than buying x10). The delivery should also be editable in the CMS per different quantities (e.g. I want to be able to set a fixed price in the database for sending x10 of a certain bike, or x20 of the same bike, and x20 of a different model may have different pricing). There will only be x4 pricing options per bike model 1. Dropship x1 (if available on that model), 2. buy x10, 3. buy x25, 4. buy x50. If they want more than this, they can go to contact form and send us an email for a quote on the quantity they require. Users must be able to pay easily without registering. Would like the design to look modern and fresh with a nice eye-catching layout and image viewer for products - think web 2.0. Please let me know if you have any questions. Thanks
