When I was going to VBAC at ANMC, they did not consider me "high risk" and put me with a midwife. At ANMC, C-section rates are climbing and vbacs dropping as new, young, knife happy O.B.s are replacing the old guard. I don't know if it is the same at the clinics or if they even "do" VBAC at the clinics. Keep us posted on what you find.
BUT...don't expect an O.B. to back you up on a HBAC. I don't think they legally could even if they wanted. Sure, they could give you prenatal "scare". But when it comes to transferring to the hospital, I always think of the Albert Einstein quote with a twist:
"You cannot simultaneously prepare for and prevent transferring."
