My go to spot for lawyers would be the Yellow Pages. If one is interested in maritime law, he is likely to note that. Or, ask friends.
Brokers is a more difficult one, although Kjell Kristiansen (sp?) is highly recommended by "zeehag" as a surveyor
in that area. A CF member
who I believe is a broker is "Happy MDR Sailor" (may be all one word), and he is at Marina Del Rey, in LA.
CF has some members from SD, perhaps one of them will have more info for you.
...AND, welcome aboard CF.
