Around my area (Eastern Great Lakes region), horses with similar qualities are listed for around $1000. Askin' ain't gettin', though, and not many horses are moving right now around here.
Me personally, I'd pay something like $5-700 for such a horse in my area. Like smrobs said, most people do expect a 10 y/o to be well broke, if not finished. Intermediate/advanced riders capable of handling what you describe are going to be looking at either putting more money into him for training, or putting a good bit of time into tuning him up and finishing him themselves for whatever job they want him for. That's going to drive the price down at the end of the day.
Good luck to you in selling him! Hopefully someone from your area will be able to give you a little more of an idea what the market is like in GA. In the meantime, you might try a site like Dreamhorse.com to do a little research - do an advanced search with your horse's attributes and your area, and see what similar horses are going for.
