Print / tshirt design tool for webshop

Hi there, I need a Quotation for a design tool (like [login to view URL] or similar) so that customer create there own print on for example posters, pads etc. They can order that, pay it, and we receive the order in backend. PDF for printing. I think a combination with Magento is superb, so we can have the payment options of magento. Please include the following: - Quotation - Have you ever made such tool already - Are you going to fit it in Magento? Or stand alone?
