Coupon Book for Home Buyers

Has anyone ever (or tried) to put together a coupon book that Real Estate agents would give to home buyers?

I was thinking of including things that a home buyer needs (or might need) such as painters, carpet cleaners, plumbers, electricians, etc. Plus I would include restaurants, dry cleaners, etc.

Thought was to get the value of the coupons up to something like $2,500. I would drop of 20 of them to each Real Estate office and additional ones would cost them the hard cost of each book, plus a little for me.

Each advertiser would have to pay anywhere from $500 to $2,500??

Selling to advertisers would be by postcard, phone and maybe by putting an ad on Craigslist for a sales person.

I haven't called any Real Estate agents yet but I know there are a few here.

Any thoughts?
