So here is the deal a client mine who is into real estate is owed commissions of $20,000 from an agent who sold a house and they where supposed to split the commision but they made the deal on a handshake and now the guy is giving him the run around and he wants me to scare the guy into paying him the money, I have never done something like this before so for you guys who do this kind of thing how much should i charge.
