I agree with Bryant this should be in a small studio. You need to secure the pole for one so you would lose some flexibilty with square footage in a large fitness club. There is a story of a woman dying in pole class in England. She was upside down lost her grip on the pole and landed on her head. The flooring was cement underneath. You need to not only consider the pole structure but the floor underneath. A small studio is best for pole work where you can specialize and focus on saftey.
At a large club if people want to get sexy they have Zumba. I have seen some pretty sexy ab intensive Zumba classes.
