Very simple online shopping portal needed for school project

I need an online shopping portal for managing its registered customers and their shopping. The customers need to register themselves first before they do shopping using the shopping portal. However, everyone, whether registered or not, can view the various products along with the prices listed in the portal. The registered customers, after logging in, are allowed to place order for one or more products from the products listed in the portal. Once the order is placed, the customer gets a reference order number and the order status should be “order in process”. The customers can track their order using the given reference number. The management of the site should be able to modify the order status of a particular reference order number to “shipped” once the products are shipped to the shipping address entered by the customer at the time of placing the order. Steps to be followed 1. Create the interface for the [login to view URL] shopping portal using HTML/XHTML and CSS. 2. Implement the client side validations using JavaScript. 3. Create the tables using MySQL. 4. Implement the functionality using the server side scripting language, PHP. 5. Integrate all the above tasks and make the [login to view URL] shopping portal functional. The above is the whole description. I have the same thing designed in J2EE. So that means all the templates and MySQL tables are already in hand. I just need the designer to alter the jsp pages with PHP as this time I need this in PHP. I'll provide the whole package which is in jsp. Budget is not much as this is for a school project, so everything should be very very simple..no mirror-cracking coding.
