How do you get a Payday Advance loan?

I had lost my job a couple of months ago due to budget layoffs and times have been hard but I just recently got a really good job. The things is I have a electricity bill that has to be paid in a couple of days or it gets turned off but my first payday isn't for a week so I was wondering how do I get a payday advance? Do I have to have good credit?I live in Bakersfield, Ca if that matters.
