Customized PHP shopping cart - integrate with xhtml design

We are interested in having someone duplicate some of the shopping cart features from this template: [login to view URL] into one of our designs. We will purchase the template to secure the code being used; however, the design will look nothing like the template being shown here - but we will keep it simple as indicated. The features we are looking to move over are: AJAX shopping cart (the same technique that is being used in the template when you click on add to cart) The shopping basket page ( a summary of their items that are in the cart) The account login section (for new and registered members) The currency selection tool (Currency types would probably be US dollar, Euro and British Pound) Paypal and Checkout Integration We will select someone who has done this type of work and can show us samples of either a cart they've done, or examples of some great integrated php work into an html template. This project will remain open for 2 days to select the best applicant. Any questions, please ask. Thanks, Ryan.
