Moving from Kansas to LA (?)

[KUJustin]

It looks like I've got a very good chance of being able to take a job in LA doing something I really love. It's early in the process, so I'm not sure yet what the pay would be, which could be a big factor, but the job itself would be great.

The drawback is I'd have to move from Kansas, where I've lived all my life, to LA where I've never been. Not sure if this is a travel forum topic, but I'd be interested to hear opinion on the likelihood of me loving or hating this. I'm from Lawrence (college town), so I'm not like a Kansas farm boy or anything, but it's still Midwest as opposed to LA.

My main concerns are:
1) Not knowing anyone
I've never really had to meet people since I've lived in the same town my whole life. I'm semi-outgoing though, and people usually find me pretty likable.

2) Cost of living
It seems just outrageous. Especially housing. I'm paying $300/month right now to rent a bedroom of a 5 bedroom, 3-story house in a middle-class neighborhood. I'm guess I'm looking at 3-4 times that in LA?

The place is in Inglewood, so if anyone has tips on that area and good places to live for a guy who's moderately cheap I'd be interested. Obviously it doesn't have to be in Inglewood, but the shorter the commute the better.
