Alright, well i am also interested in acting. I know it does not happen over night so here is what you need to do.
First you need to get involved in as many acting classes, lessons, plays, anything that will look good on a resume.
Then you need to get head shots taken and send them with your resume to acting agents.
If an agent likes you he will respond to you. After that it will be much easier, because you have an agent.
Good Luck.
I also sent you a link with acting agents in the LA district.
