How do I get my CNA?

My names Stephanie and I am turning 20 this month, and I need to do something with my life, and I always wanted to be a nurse. My cousin who is younger then me just got her CNA, and I want to get mine now because she said it only takes a month and it doesnt cost that much. I was hopeing somebody could tell me were in California, preferably in Apple Valley area or VictorVille I can get my CNA. And I also wanted to know if I could get it done for free or get a special loan. And how much it normaly costs.
