Salons that can dye my hair an unatural color?

I'd really like to dye my hair bright blue, the problem is I've tried doing it before and it didn't turn out that great. I was wondering if there were any places in San Francisco that dye people's hair unnatural colors? Less expensive places are preferable...Salons that can dye my hair an unatural color?
