Website similar to tshirstudio.com (Spanish speakers preferred)

I want a website with an t-shirt personalizing script exactly like the one in [login to view URL] but with much less products (about 6 or 7) I will provide the logo, photographs and texts and the design of all static pages, I only need you to create the aplication and install it. I will also need a very simple payment gateway integration for the products. Budget is low, but the winning bidder will be getting more work in the near future
