Hey. I happen to be in the greater Nashville area. The Refuge Center in Nashville offers a group of counselors that are experienced in EMDR and they work on a sliding scale. Perhaps give them a call? They are the go-to resource for folks without a ton of spare cash or slightly less than stellar insurance.

If they can't help you directly, they could refer you somewhere that would.
