Build a printing website with file upload

I'm looking to build a printing website very similar if not exactly to this website: [login to view URL] My site address will be [login to view URL], this is hosted on the "Hosting24 web host servers" I would need the front page poster order and image upload, live shipping rates that are accurate, and Paypal payment gateway integration. Website design is not needed but I will look at submitted design ideas, only the architecture and development of the site need be created with the ability to design in Dreamweaver. Also I need the pricing options page and a page to add products that are already printed/vinyl cut with size options for instant purchase. This is NOT a rush job. I plan to officially launch the site in a month or so. Take your time to lower your cost and do the work right, but I need to have an idea of when I will be up and running. I am familiar with HTML but would welcome other formats. If you have ideas to make this better through experience I welcome your input.
