Four people in the last week have gotten quotes and mockups for big signs ($10K+) from her, then turned around and used the info to get a better deal from a competitor. And using the mockups as a base for the design, so they get a head start in the process with Company 2.
Basically, she is doing all the work, and the competitor just knocks off some money off the price (which they can do because they aren't doing a lot of the initial work - that's been done by us), and gets the deal.
We have wording in our forms that they can't use the mockups unless they pay for them, but enforcing that is costly.
It's a waste of hours of time for the sales rep.
I suggested a "good faith" deposit to try and ensure she isn't wasting her time, but that idea was soundly shot down.
Any other suggestions?
