Sales promotion - something interesting and maybe different

In my capacity as a management consultant, one of my clients is stuck for ideas, so I thought I would put it out to see what others might come up. The busines is a Turf business in Australia (also know around the world as lawn, sod, grass) and it wants to run two promotions. The industry is not known for anything particulary exciting when it comes to promotion. We are looking for ideas, as many as you can come up with from which we may pick one. There are two promotions, one is simply an email promotion to businesses on our CRM database (B2B) who use our product, but don't use us. The second is a google adwords offer to residential customers. We have done a goodle adwords promotion this month and it has been successful but it runs out soon, so we need to come up with another compelling offer. I think a budget of about 4 hours for the work should be enough. I will send further details to the successful candidate including the website etc. If this works, I have a lot of marketing work that this client needs on an on-going basis.
