506638 printing project

I am developing a website and I need some help with a few parts of the project.... 1. I need a calculation script created very similar to the instant price calculator here: [login to view URL] I will have a few different fields but this is very close...it should have a place where the admin can easily edit the cost involved with each option so we can easilt change our price... 2. I need the shopping cart backend created that will have the ability to process orders and bill the clients credit card from orders like the price calculator created above. we also need the abilty to upload files after or during the order to our FTP. If you have any sugestions or can easily setup a nice CMS.. I am open to ideas...
