call for price - add to cart

[balihr]

How can I allow "call for price" products to be added to cart?
I need a customer to upload his/her file and place an order, and then i define a price depending on the file sent.

Could you please explain a little more?

Here's an example situation:
I offer printing services. You can upload a document with 20 pages to be printed or 500 pages to print. It can be a3-a4-a5 format. It can be double or single sided print. So, after you place your order, i review the document and tell you the price.

Define a base standard per page price
i.e.
single side
a3
standard bond

Add attributes for
double sided add $
a4 +$ - a5 +$

Other paper types add$

OK, I understand attributes, but this IS NOT what i need.

Zencart doesn't know how many pages are in the uploaded document so it would require customer to input how many pages there are. So, you can upload a document with 500 pages and say there are 200 pages, go to checkout and get a price lets say 200*1$=200$, choose online credit card payment and instantly pay 200$ but should regularly pay 500$. Now, I have a problem because my shop created a "pre-invoice" and received payment, but i can't deliver it because THE SYSTEM issued an invalid invoice. I know that legally it's not my problem and I can deliver only 200 pages because the customer said quantity=200, but this is something I desperately want to avoid (you know how it goes - the customer is always right). I think it's much much better to receive the document, calculate the price manually (include some extra discount if I feel like it) and notify the customer about the price.

So, is there a way to have a "product call for price" added to cart?

What would be added to the cart?
There has been no definition at this point

One can refund and notify if there is a 500 page doc and payment was only for 200
