Need Web2Print / Web To Print Solution in HTML 5 for OpenCart

We are launching a personalized gift shop. There will be more than 20+ Categories and 100+ products. We need a web2print / web to print system created / modified if you already have one. The system needs to be integrated into opencart. The design can be for any products like greeting cards, mugs, t shirts, plates, picture on softtoy, mobile cover, etc. In most cases, a pre defined design is given and customer can add images on blank location within the background image. Plus, they can additional images if required. Customers can also select shapes, which will be added from backend. And finally, text can be added as well. The designed should be converted into high quality PDF or JPEG and emailed to us when the order is placed. For some products the design will have multiple sections, like greeting cards, which will have front, left inside, right inside and back cover. We will need the settings for that in the backend. This needs to be done in HTML 5.
