Couple questions.
Are you union affiliated? Are you signed with your agent, or just freelancing? There are many different relationships possible with an agent.
As far as proper etiquette regarding teminating your agent's services, a simple certified letter stating your intention is all that is actually required -- a personal appointment isn't needed. This is a Dear John letter, not "Getting to know you." If you are actually signed, you may wish to just allow your contract to lapse and simply not renew. But union or not, if you are signed to an exclusive with him, he has the legal right to any future commissions due him for the balance your current contract, usually one year. Apparently this guy won't even realize you've moved on. But to cover yourself, the brief letter I recommended is the safe and professional way to go. Better safe than sorry.
If you're agent is union franchised, you may still have the right to prematurely terminate your agency contract. Here is a reprint of my recent post on the subject:
"SAG does indeed have an "escape clause" allowing its members to terminate a contract with their agent prematurely if certain obligations aren't met, in your case, failure to book you sufficient work. It's called "The 91-Day Termination Clause," and stipulates that if your commercial agent has not booked you at least $3,500. of SAG work in a single 91-day period, you have sufficient grounds to terminate your contract early (for theatrical agencies, it's 10 days of SAG employment in 91-days). Assuming that you are a member of the Guild, be advised that your agent MUST BE SAG FRANCHISED in order for this legal loop hole to have effect, so don't just assume -- check with your local SAG office to be absolutely certain that they are.
Never leave a voicemail or email, always make anything this important legal by putting it in the form of a written letter, and be sure to have it certified. Make your termination notice short and sweet, stating that you are invoking the 91-Day Termination Clause, thank them for their service amd consideration, and better luck with your new agent!"
