cformsII – what is practical limit to number of forms per site?

I have a web based business directory with about 150 businesses listed. I would like to have a customized contact form for each business. Is it practical to have a separate cforms form for each business?

Or is there some sort of way to create a single form that would somehow had a condition in itthat will pull the appropriate business email address into it from each business listing.

Not sure if I’m making total sense or being clear enough of my need. Basically I want to be able to have each business know that the email they are receiving originated from my site. That is my need.
