Zen Cart Customization

I need my zen cart to function like a web to print site. I've done as much tailoring as I can do. If you have a complete solution for Zen Cart web to print, I would be interested in that. If not I need a custom product type for a printed product, custom attributes with dependent attributes, and shipping from multiple locations based on customers address. My website is [login to view URL] an example of how I want my cart to function is [login to view URL], [login to view URL], nextdayflyers.com. I'm not looking for exact replications of those carts functions because I know zen cart maybe more limited then those sites but so far I'm really close to what I want. Please quote job in sections and as a whole.
