I recommend asking smaller personal training studios in the Atlanta area regarding independent trainer policies. Larger franchises usually have staff employees serving as trainers and refrain from hiring independent trainers. I’ve only seen a few places–military bases and the YMCA–that take independent trainers–and that was sparingly.
Another option is to take the training–program and equipment–to your customers. You’d be surprised how many people like the convenience of a guided workout in their home! Convenience and flexibility are great selling points! And you’ve got the neighbor factor that can facilitate indirect marketing!
I hope that helps!
