Hi and good luck to your baby turning project!!! My first was breech and we tried EVERYTHING to get him to turn but I ended up with a c-section. The one care provider I've identified in the city who will do vaginal breech deliveries is Elias Sabbagha at Northwestern. I would contact him asap and have a consult. My midwives (at Northwestern) and the docs who work with them attempted an ECV for me at 37 weeks when I was pregnant with my son, but it was not successful. Still, I would give it a shot.
Oh - and send me a message - I have the Hypnobabies "Turn your Breech Baby - YES you can!" guided visualization CD. I actually got this when baby #2 ended up breech at 31 weeks (happily, she flipped before I got a chance to listen to it!) I'll mail it to you, or you can swing by and pick it up if you're in the city.
Don't konw who your chiro is but Dr. Sean Manning in Oak Park is The Guy to go to for Webster maneuver, I've been told. (I saw another, Dr. Nella at Bucktown Chiropractic, who I thought was quite good, though it didn't work for me. Still, I'd also recommend her).
Good luck to you!!! Although my first was a c-section, I had my second child this past summer - an awesome drug-free VBAC.
If you do end up scheduling a c/s, make a c-birth plan, ask for what you want, go through it with your doc/midwife ahead of time etc. (And know that it's OK to be disappointed in the whole thing. And then slap anyone who tells you, "At least you have a healthy baby - that's what matters." This is like saying, after a car accident in which you're badly injured, "at least you're not dead." True, but it misses the point.)
