I saw some university had a room-sized omnidirectional treadmill, but it also focused on keeping you near the middle, the benefit of being room-sized was that you could break into a sprint and the treadmill would be able to keep you on.
Pretty sure that you won't be able to get one. You could look into setting up redirected walking if you have a decent-sized VR area like these guys:
