Dr. Garner was my doctor for two of my earlier pregnancies. With my first birth, I had no idea what I was doing and I had the textbook mainstream birth (pitocin, epidural, episiotomy, etc.). During my second pregnancy, I wanted a natural hospital birth with no unnecessary medical interventions. Doctor Garner gave me mostly no trouble with my birth plan, however he was convinced that I'd have to give my newborn the standard eye drops after birth (I didn't) and made a small fuss out of that. He ended up not being on call for my birth and I had someone else attend that's in his practice, so I can't really say whether or not he's a great pick overall. I do know, however, that if I ever decided to have another hospital birth, I would choose several other doctors before him.
The doctor with the best reputation for being natural and VBAC friendly in central AR is Dr. Kevin Breniman at Cornerstone Clinic for Women. He comes highly recommended by natural birthers as well as the midwives in this area.
As for a VBAC friendly midwife, I'll PM you.
