Hi Talia,
I am glad that you are being proactive about getting your baby into the vertex position. Although, most doctors and midwives are not particularly concerned about the baby's position until around 32-34 weeks.
However, you can look for ideas to help your little one head downwards on the blog
"Explanation of Fetal Positions"
As for an acupuncturist, I usually recommend Francis Goodwin. Her number is 212 414 0388.
Take care,
Deb
