Design and set up of online bookstore

Design and implementation of online shop for bookstore using PHP/Mysql. The contactor will design a website using our corporate colours and will implement this design into online store software and ultimately deliver the new site to us in working condition (we will then install the final website and software on our servers). 1. The website will sell books and manuals about education, courses and training. 2. The software and design provided should feature search functions to allow visitors to find the book products quickly, allow us to update product with prices, descriptions (with pictures of book covers) and other info in a user-friendly way. 3. Visitors should also be able to alculate the shipping cost using information that we have put in and calculate sales tax. 4. We should be able to provide coupons to customers that they can use on the site. 5. Customers must be able to pay by credit card and/or print out an invoice from the system. Please provide specific examples of similar sites that you have made before if you are bidding! We are particularly interested in nice designs that go beyond the normal templates available with the usual shopping cart software that is available. Many thanks Kevin
