The complaint you filed at the State Bar association will probably take a very long time. But, if they find he did something wrong, they will make him pay the money back.
Of course, if you want to move ahead anyway, sue him in small claims court. It costs very little and you can do it yourself. Ask for the $1000 back, as well as interest and court costs.
Believe me, no lawyer wants it made public that a client is suing him. That would be very bad for business. Even if you sue him, that doesn't stop the complaint at the Bar Association. You won't get paid twice, but they might sanction him for doing this to you.
