Courtenay Grabowski has been a doula at a couple of my homebirths. She was great! (she posts here as courtenay_e -- you could pm her) I would also recommend the doulas at nineshortmonths, but I believe that they will be on vacation in July.
We worked with Alicia Montgomery from The Cradle of Birth (www.cradleofbirth.com). She was amazing - we took a Bradley class but would not have gotten through my labor and delivery without her!! She also is great about post-partum support - she came back to the hospital to help me when I was having trouble breastfeeding. She's awesome
