315719 Database Driven Website

We currently have a static website which displays multiple categories of plant (construction equipment) that we auction off on an onsite auction every 6 weeks. Our catalogue is based on a number of categories. We want to have a fully database driven website where all the pictures and descriptions are dynamically displayed based on a database. We will also need an ADMIN site to be able to add / modify / delete seller info, buyers info, item pictures, item description, categories and also be able to generate printable reports (Items sold, unsold, buyers and their purchases, sellers and their items and etc). We should be able to upload new items and their pitures from the ADMIN site as well as attach the sellers info as well as the winning bidders for our invoicing and managing our items. The thumbnails when clicked must display a larger picture as well as other pictures of that item. The product catalogue must be dynamically generated and the ADMIN site must allow us the ability to manage this information dynamically. So we won't require any further programming work. Please type "WESST" in your replies to receive any attention. Only intrested in developers with good communication and prompt response throught out the project. Must be contactable and work must be tidy. Code must work flawlessly. Our website is [login to view URL] No preference on scripting language (ASP, PHP and etc), whichever works better, efficient and reliable. Only send work refferences of relevant and similar websites.
