The person who did the PLR on me i met through the DAvid Icke Presentation in Melbourne. I suggest that you do a bit of research in your area (you've probably already done that) and ask lots of people involved with spirituality etc. People that channel often do that or have contacts. The only thing is finding someone who is reputable and has a reputation (good).
Meditation is the key. I have heard that its better to be regressed under meditation like i was than under hynotherapy. IMO
