Black hair to Playboy blond hair at Aveda, how much money am I looking at?

I have shoulder length hair with Betty Page bangs, currently I have black hair that has just recently been deemed as healthy again. It, at one point, was extremely dead and fried do to countless times of dying my hair the colors of the rainbow and quite a long stint of pure white hair (using just bleach to get it that light.) Now I am scared to dye it blond on my own but I would love to have to have the color of Kendra Wilson or Jenna Jameson-- they both have gorgeous blondes! I've never had a bad experience at Aveda so really trust their students and want to get it done there, but how much should I expect to spend for this?
