If you cant locate a coach or pro near by, you could always check out the league players at your local center and talk to those bowlers to see if any would be able to help. They would know who they would go to if they were having problems. Also ask around the center to see if they know anyone there who could help you out by watching you bowl and being able to pick up on what your doing. The videos online are great but they can't give you the feedback that you need.
