i don't have a tuturial, but i can tell you step by step here. the problem with most people trying to do atm for the first time is they try to flick it of their neck and go around, but that makes the trick harder. instead bend your knees and push up letting the ball come off your shoulder and carry your head around the ball. the majority lift from the ball should come from bending your knees. this will make it much smoother.
