I've hit a brick wall so to speak with a site i'm working on. initially i was going to set it up with zen cart but i'm not sure zen can do what i need so please if you have any suggestions on if this is possible with zen or possibly another way i can go about this .

The site is selling food to restaurants. The prices change daily (if not sooner..lol) the site is merely to show what is available for purchase, no sales will go thru the actual website.
however we would like for the viewer/customer to be able to fill in an order form and be able to print & fax to the parent company - where the reps would then contact the customer back with the actual price and payment options - b/c the customer would have to be approved for credit and such.
there are well over 20,000 items (which is why i was looking at zen b/c of the easy populate..lol)
I was hoping to use zen b/c of the categories/search features/etc


some things i've thought about that maybe i can do with the zen

do not put any payment options and then it would just send a order form?
is there a way to put no price and it still be able to be ordered?

I'm kind of at a hump that i can't get over ... any and all suggestions would be greatly appreciated.

Thxs for reading my ramblings
