Design of Website for Picture Uploading and Printing, and associated database Progamming

I wish to develop a website that will allow users to upload their digital photographs (up to 40 mb datasize) to a new website in order to print them on to Canvas.

The site should allow the user to select the size of canvas they wish to purchase - and provide a "Sitting Room Wall" that allows the picture to be previewed in proportion to a couch and a table lamp. (If you search for "prints on Canvas" you will find many examples.)

Once the client is happy with the size, they should be able to select some simple options, such as "wrap aound" and "depth of the frame" to be used.

The finshed product should then be sent off to a Shopping Basket for payment processing. We want to be able link/pass the Orders generated directly into Sage50 acounting.

We have a detailed Specification document we will make available to any serious responder.

The website must work across Microsoft/Apple web paltforms.

This is phase one. We have additional phases and other work once this first phase is completed.
