This is is actually what is currently happening in my market. My customers are increasing their volume each month while those that aren't using it are going down. The only problem is the market is quite fragmented so this approach only works if I have a customer in each market. I am working on solving this problem :) Edit. I should add that I have offered a discount in return for being able to publicise their use. Unfortunately, everyone has declined the offer.
