Look for clerk, legal secretary, and paralegal jobs. There are a ton. Then you open the door and gain experience.
What a lot of people do not get is that law school does not teach you how to be a paralegal. It is the equivilent of taking a doctor, newly out of medical school and dropping them into the medical billing department and expecting them to know how to do that complex insurance paperwork.
San Diego is a tough market because there are three ABA law schools dumping out hundreds of graduates every semester, most of which stay here. The competition is very tight.
Many people have gotten started by getting a small office in with attorneys who practice in the area you want to practice in, and trading work for the office space, which gets you free training from them; and also while taking small cases on the side that you can figure out how to do - and pay the bills with. Get good at one thing, like unlawful detainers or filing simple bankruptcies, and advertise like crazy at a big discounted rate. It will at least get you started, get you some experience you can put on your resume, and not leave you working for free. It's not as if your bills magically disappear while you are doing all the free interships that people recommend.
My 2 cents, from one who has also been there and survived it!
