Yes, vbac is an option in a birth center and/or home. The trick is finding a provider willing to support you. (Or go unassisted - a whole other ball of wax.)
Sadly, no birth centers are really within a reasonable distance of Nashville. Seems like there's one in Waynesboro and another in Crossville? I may be making that up; it's been awhile since I checked.
But there are several midwives. http://www.tnmidwives.org/directory.html has a list. Seems like Tender Beginnings in Franklin had birthing suites. And I know the midwives in Hendersonville do vbacs, because it's in their "stats" on their website! So definately worth calling around.
As for insurance... mine is Cigna and they were willing to cover midwives 100% so long as they were in a "licenced facility." Which for me ended up being the midwife group at Vanderbilt hospital. (I didn't mention them earlier only because you're trying to avoid the hospital. But I got my normal natural vbac with them. http://vanderbiltnursemidwives.com) But I don't know about insurance and homebirths. Ask about that when you call around, too.
I'd also repeat your question here at the Nashville Birth Network yahoo group. http://health.groups.yahoo.com/group/Nashvillebirthnetwor... Those ladies will probably have a lot of leads for you.
And if you haven't checked out ican-online.com yet, you should. Particularly consider getting onto their email list support group. It's high volume, but worth it.
As for getting your husband's support: May I suggest Bradley birth classes? Mine was on the fence until the classes began. He transformed into my biggest advocate, defending me to his family who thought I was crazy. I've even heard him educating other women on Pitocin and AROM. He's something else now! Our teacher was Bohdona Fasani, but there are a few in Nashville. And one student teacher in the Murfreesboro area who probably has a discounted rate, if money is an issue. http://bradleybirth.com/Main.aspx
Whew! That's a lot of links! You sound highly motivated and that will go a long way to a successful vbac. If I've left anything out or you have any questions, feel free to send me a message!
Blessings, L.
Edited to add: "I'd like another baby, but I'm not going to bother getting pregnant if I know for sure it'll end in a c-section."
Your feelings are your feelings. Let them be what they are, whether they're pc or not. Many many women have limited their family size because they hated their csection. You're not the first to have that thought, and you won't be the last.
Also, one more link for you. http://tinacassidy.blogspot.com/2008/01/our-new-baby.html A vbac home birth from one of the big shots of the birth scene.
