Suggestion for a price Quotation Cart system ?

Hi!

I am currently working on redesigning a site selling custom promotional products. What i want is a system working like that:
The potential client browse the product catalog. If a product is interesting, add the product to a “cart” continues browsing for other products. When it’s over, fill a form and ask for a price quote of all the products (in fact send a email to somebody that will give the quote). The price quote is not made by the system. An person will do it. There’s no payment via the website. It’s just a price quote system.

Now, I dont have the time, and i dont think i am good enough to program that.

Do you know good system that would do what i want. A good compagny to look for?

thanks!
