Don't drop your price, it gives the client the impression that it was too high to begin with! Let them know why your price is worth it, tell them about your expertise dealing with stumps, tell them how your service stands out from the rest(don't bad mouth the other guy though) tell about the finished job, mention installing soil and seed for a bit more money. We all know that cleaning up chips is a pain, get paid for it! Give them a reference to contact, someone you have worked for and loved you, and someone who had a problem that you took care of, resulting in a loyal client. Don't play the low bid game, Under promise, Over deliver, take the extra step to develope client loyalty, bring the garbage cans up from the curb, listen to what clients are telling you, remember them on a personal level, Sounds like alot of BS, but it works!
