I have High school diploma but havent attend university, just took some ESL clases at Glendale Community College to learn English.
Im looking for 1 or 2 years program at school to get a certification of computer hardware and networking. Would you please answer my questions if you can? Which college or school do you recommend for these clases in LA area?
How many units should I take?
Do they have financial aid?
How is the market demand for this job in California? What is the average sallary?

Thanks in advance.
