531728 Order page

I need a php order page for my website as simple and as easy as [login to view URL] i basically need this page replicating, allowing my customers to pay via paypal and allowing them to add multiple canvas'. I would also like an ajax info menu adding like the one on the page to allow my customers to see what they are ordering and it would need to update when different options are selected, like the site i linked to. I also need a shopping cart tab adding to the site. I do not want to offer a "my account" feature, just a simple checkout via paypal where they enter all the details, proceed to pay and then i can manage their orders which would be a simple admin control panel where i can view orders, download artwork/photos, change order status (i.e shipped) which would send them an email when it was changed. I need this system within 7days, with all css to fit into the expandable image i have attached. I really want incredible css on this, i want it to look clean enough to fit in with my image, work examples of forms are a must.
