I would be surprised if anyone would deliver a breech baby vaginally these days, unfortunately. My second baby was breech late in the pregnancy, and I was planning a homebirth with a midwife. She had been in practice for about 40 years and had delivered many breech babies vaginally, but she told me she couldn't do it anymore or she would lose her insurance (or something like that).
BUT, I had success in getting my breech baby to turn! I think I was about 35 weeks along when we found out that he was breech. My midwife instructed me to lay in an inverted position for at least 15-20 minutes, several times a day, as much as I could possibly do it. I took my ironing board (with the legs closed up) and put one end of it against the couch with the other end on the floor, and I lay down on that with my hips higher than my head. Each time I did this, it was the longest 15 minutes of my life - it is incredibly uncomfortable. Everything goes up to your chest and it is terribly difficult to breathe, but I think that is the point. The idea is to use gravity to get the baby as far up out of the pelvic area as possible so he will have more room to turn.
I was also advised to use heat and warmth to encourage the baby to move. Put something warm (like a hot water bottle) low on your belly by your pelvis where you want the baby's head to be, and put something cold (like a package of frozen veggies) high up on your belly where you want the feet to be. The baby will apparently "head" for the warm spot, trying to get away from the cold.
And when you're not inverted or doing the heat/cold "therapy," you can do things to help the baby turn with all of that room he has!;) The things I remember are:
1) Pelvic rocks - you probably know what those are, but if not, respond to me and I will let you know,
2) Try to keep your belly below your back when you are not standing (ie. do not recline backward, but lean forward) this uses gravity to encourage your baby into the optimum position. This is not easy because there are times you just want to recline with your feet up. Try to resist that as much as possible (I still did it a little bit), instead, whenever you have time to rest and want to, lie down on your side (I believe the left side is preferable).

I also read a great book (when I was pregnant with my first) called "Sit Up and Take Notice." You may not have time to find or read a copy of it with only 6 weeks left and a 2 year old to take care of, but it is all about getting your baby into the optimal position for birth, and a lot of it has to do with how you sit (no slouching or reclining backward) and your general posture. It's all about gravity, and you can position your body to let gravity work to get your baby into the best position for birth.
I cannot say that I know for sure when my baby turned, but I remember one night, a couple of weeks after starting the "inversion therapy" on the ironing board, I woke up in the middle of the night to my baby doing some kind of gymnastics in the womb. It didn't really feel like he was turning in the vertical position, it felt more like horizontal movements back and forth across my belly, but at my next visit a few days later he was head down!! And I don't think he could have had a whole lot of room to move in there because he was a big baby - born a couple of weeks later at 10 lbs. 6 oz. - and he came out in one push after only 2-1/2 hours of hard labor (that was a surprise to me, but I won't complain). He must have really been in the perfect position!
Another mom asked a similar question a little while back (my response is there to, just about exactly what I have written here). Here is the link:

Hope this helps and hope you are able to get your baby to turn!
