As an update I did find a Webster technique trained chiropractor, Belinda Forsyth. She's really helped me with hip and back pain. Unfortunately neither this nor the acupuncture/moxibustion, nor exercises at home, swimming, etc. have worked and I still have a breech baby at 37 weeks so am booked for a c-section at 39 weeks. I tried A Mother's Touch but they weren't able to help as the person who works with breech positions was on vacation.
I have to admit, I suspect the high success rates with these treatments are due to the fact that 95% of babies turn head-down by term, so pretty much any treatment will "work." I wish I had saved the money and effort with all of these treatments and just had massages to relax myself and mentally prepare for a c-section instead.
