There's been a few studies showing that moxibustion has been effective in turning breeches. In the studies it was usually done multiple times (daily) over 1-2 weeks. Here's a few studies I found on it:
Moxibustion for correction of breech presentation: a randomized controlled trial.

Acupuncture plus moxibustion to resolve breech presentation: a randomized controlled study.

I'd also go to a chiropractor who specializes in pregnant women for the Webster Technique. Another good way of getting baby to turn (and be in optimal position even if they are head down).
The Webster Technique: a chiropractic technique with obstetric implications.

And no harm in trying the Spinning Babies techniques too.
