The best and least expensive way to move from Pennsylvania to californa.

I have been wanting to move to californa for a while. I am currently attending college and don't plan on leaving till I graduate, but looking for good advice and a little help. And also ideas of jobs that could be done once moved to californa. I am a criminal justice major at the moment so I winder if a cop is good in that area. Is there places that are better than Hollywood as well ? What is or are the best places in californa to go to,that are the nicest and best areas for a younger man to live at. I'm really just looking for some advice. It would be much appreciated.
