AtlCSIP- A few years out of date, but there was a guy at Tara field near Hampton doing tailwheel for very low cost in a Taylorcraft, the old guy who runs the Cornelia airport had another one, and there was a retired AF guy at Mallard near Hampton doing instruction in a Cub. These are just the first few I thought of. You need to make some calls and they will turn up. When I was after my signoff back in 2004 I had them lined up and literally turned a couple down. No shortage of men and machines, but they do not advertise because there really is no money in instruction after insurance and renting out a tailwheel airplane is unworkable due to risk.
