How do I cfg Zencart to 100% wholesale mode

Dear All,
Could anyone please help with this?
I want the zencart to be a compeletely wholesale tool
I can send the pricelist by mail or fax to the customers,so there is no need to show the prices at all(the tax ,shipping cost can be shown,since sellers don't compete on those things much).but I'd like the customers to login and place their orders within the website,(the showcase mode does not allow the customers to place the order),so I can use zencart's strong statistics,then this could be far more effeceint than sending both the pricelist and order forms then collecting orders by mail or fax
so the question turned out to be, how can a customer place orders in showcase mode if he/she already has the pricelist? or can we make other modifications to have the zencart fuction like this in ordinary mode?

TIA

BTW,Thank all the Zen team for their fantastic jpb!!!!

You could set up the Customer Details to only allow shopping when an account is approved ... otherwise set it to show the products without prices ...

If a customer is approved, when they login they can now make purchases ...

I have a version of Zencart I use for some of our wholesale customers, all of whom order the same products, but have individual pricing, from which I stripped all the pricing info out. That includes tax, shipping, etc. (Delivery is by our route salespeople.) If you're interested, PM me and I'll see if I can remember all the files I had to modify.
