Don't be such a cheapskate! You pay for what you get. Hire a good reputal pool contractor and you won't have some drug user, or rip off artist coming to your house and gouging your mothy pocket book. I suggest you check your local BBB and ask some of us pool owners for the company that built our pools. You just have to be willing to pay a little more for good quality. Since your in California, I bet you got a big bottom line anyway.
