Add eCommerce to existing WP pizza site

Take our existing pizza site that has menu items and their prices and add an eCommerce component so that customers can order food online. No payment gateway needs to be incorporated at this time; orders will be submitted by email to the pizza store for disbatch, and customers will pay on delivery. All frontend components will be provided. You will work with our frontend team to complete this project meaning they will provide you with the HTML and CSS for the look and feel. You will find the eCommerce plugin or build one from scratch to fulfill the needs of the project. Each item will have an "add to basket" button. Some items have options to be selected before being added to the basket such as size. These options will have a price associated with them that will affect that items final price prior to being placed in to the basket. The basket should show a subtotal at all times. Customers should be able to create an account that will save their delivery details, their phone number, address, email address, prior order history. Customers should also be able to save set baskets, meaning they can save a meal to order on a regular basis. Maybe they order a large pepperoni pizza with two Cokes all the time. They would be able to add that meal to their basket with one click rather than going to choose a large pepperoni pizza and then ordering the two Cokes in a separate step. With so many free eCommerce plugins out there, this should be quick and easy money for the right programmer.
