Is there any reason why I can not use this for a quoting system?

My client wants to call all clients to finalize prices and orders.

In order to do this I assume I would:
1. have all prices set to $0
2. change the "Add to Cart" text to "Add to quote"
3. Change any submit order text to "Submit for quote"
4. have a admin email with contact info and all k2 items added to quote.

I assume this can be done, but I wanted to make sure before I purchased it.
