Is it hard to get part time work in one of the studios in Los Angeles? e.g. paramount, mgm etc...?

I'm moving to LA soon and would love to work as close to the film industry as possible, as I am an actor, I would like to see and be as close to the action as possible. I'm pretty much open to any kinda part-time work. Also I would like to intern for an agent and or a manager to discover the secrets to the business of making it as an actor. Any advice,tips would be great. Positive people preferably. Thank you guys.
