add Zen cart & integrate into my website

I have a site with many pricing. I like a provider to install zen cart in my linux space,( i have it in my control panel) link all my pricing in my pricing table, to a page with custom fields (provider need to create the link) . Then exit to check out. All this pages need to be in my website template. Buyer do not need to process thru credit card but shopping cart just need to collect the buyers details & order where i will process manually. (this site has a sample that i like mypixelprints(dot)com) I will also need advice on how to add & maintain the links & shopping cart myself in the future. See the file for more info.
