1) Save up in advance. Get a job where you are; aim to be there a year tops. Spend no dime you don't have to. You'll probably want to have $3000 ; but with luck you can make do with less. When you've got the money, you've got enough for an apartment and food, and bare necessities for 2-3 months; spend all your effort finding a job after you've got an apartment. It's probably best to get a 3 month lease, since you might want to move to be closer to work, or move once you're more familiar with the area.
2) Get a job. Start applying out west until you get someone who'll give you a job. Places are less likely to want to interview people from further away, but college grads are a bit of an exception. Especially since you're coming from college the job might pay to relocate you. Note; they won't pay ahead, they'll reimburse you. Remember, it might be as much as 4 weeks from when they sign you before you see a cent.
I did number 2. This was just before the dot bomb crash, so while I found a place who was willing to reimburse my plane fair (they hired me on friday to start on monday, with phone interviews only... they were desperate for a sysadmin), and I even got them to agree to reimburse me within a week. I had 1500, and I was lucky enough to know someone in the area who let me crash at his place. However, $300 for the plane ticket; money to rent a car (which later was reimbursed); gas driving 60 miles round trip; $800 first months rent $500 security deposit. I'm lucky I had room on my credit card when I made this jump; or I'd have been short being able to get the money together to get the place I did.
Either way you look at it, in order to have a chance at being successful, you'll need a non-trivial amount of money, so unless you know of a place who's willing to do everything to get you out there (back in the day, MS would handle plane tickets/car rental/and set you up in a hotel for a month so you wouldn't have to do out of pocket and later get compensated), you should get a loan from your parents, or start working where you are.
