Hi Phoenix -
I had my first guided past life regression a couple of months ago. I found a QHHT practitioner (Delores Cannon's method) at the below site. Some practitioners offer free full readings. In the Healing Practice drop down menu you can find the free options.
https://www.quantumhealers.com/The practitioner and I talked via email, had an initial conversation over Zoom, then we scheduled the free regression. It was great. I would be happy to share the name of the practitioner I used as well if you wish. I don't know if she is still offering free sessions or what her rate is currently.
Good luck!
