@lodp,
Definitions of retainer (in this case):
a fee charged in advance to retain the services of someone
money paid by the client to the lawyer to obtain a commitment from the lawyer to handle the client’s case. A retainer is a deposit against which the lawyer’s fees are charged as they are earned. Some retainers are refundable and some are not. You will need to check with your lawyer.
A pay me nt made to an attorney to secure his or her services. The retainer is placed in a trust account and, as the attorney works, the charges are deducted from the retainer until the money is used up.
So i'd guess that you'd have to pay $2000 first as a deposit and the $200 more each hour on top of the $2000.
I hope that helps
