Online interactive garment designer

We need to make a web app to customise our garment orders. Something similar to this: [login to view URL] 1. The initial project will include 3 vector jacket designs. 2. Every garment will have front, back and lining graphics (the link above has only the front graphics). 3. Completed garment design will be recorded in a database. 4. Completed garment design can be saved as a pdf file and be emailed to both the customer and us. There needs to be a backend interface which will have these features: 1. We can add more designs by ourselves or by other designers. 2. Customer details and orders can be viewed and exported as pdf file for printing. This project can be produced with Java, HTML 5 or Flash. We will need to have a complete copy of the software including all source code. The web app will be added to our existing web site http://www.daylightschoolwear.com. We will provide graphics from the web site so the app can match our overall theme. After the initial project is finished, we will eventually add more designs and we will need someone to make them for us. So we will be looking at a quote for extra design as well.
