If you can get your hands on some One 'N Only Colorfix, I've found that is an excellent colour stripper. I was able to get dark red/black out of one of my friend's hair with only one application, and it's easy to use with minimal damage to the hair.
I've had that problem as well. Most hairdressers tend to be very cautious about what they are willing to do, as they don't want to be the one catching the blame if the process goes wrong, and bleaching/colour stripping is one of those things that it's rare to find a hairdresser who is willing to do it. But that doesn't mean it can't be done. As I said, I've gotten my friends' hair from various shades of dark brown and black to light blonde with just one or two colour strippers and a light bleaching.
