I haven't used a processor in over 10 years, been doing it myself. Didn't have the time this year so I dropped one off at York's in Barnesville, out 36 towards Thomaston. By far the best I've had. Open till the 15th. One of a few if not the only around there still open.
York's Deer Cooler
1006 Hwy 36 West
Barnesville, GA 30204
His business has really, really taken off lately. Last season his joint stayed lit up like Fort Knox and had cars outside all the time. Rick is a really friendly guy and has evident experience as a butcher and processor.
And yes, the jalapeno and cheddar anything there is indeed crazy good!
Recently used Steve Bishop in Covington. He's at the corner of Hwy 11 and Hwy 142 just a couple miles south of I20. His prices vary depending on the size of the deer, so that's nice. Basic cut for deer up to 75 lbs is $55. Then $65, then $75 for the largest deer. $1 per pound of sausage.
Don't quote me on the prices, but they should be pretty close.
