For entertainers that refere me I thank them, and promise to return the favor. For anybody else I give 10% cash, a hardy hand shake, and a sincers thank you, because I want them to do it again and again, and again. When you send them a thank you card you can bet that will be their last referal. If you try to network with Hallmark cards you are waisting your time, because "Money talks and (you know the rest)"
