That's tough being thousands of miles away. My best quick thought is look up the schools he would be interested in, then look up pitching coach and Google him. If he is on twitter or instagram (in all probability he will be since that is what kids are on now), then look who he follows. Lots of times, they follow someone who they respect their philosophy. I know that is a VERY long way around.
Be aware that the Pitching coach and / or the head coach could easily change. My son is a red shirt sophomore in college and both left this year for another opportunity. He loved(s) both of these men. When he was being recruited, he asked (with my prompting) what the style, training, expectations, philosophy they were of each PC and HC he got recruited by. They all gladly told him. But this year he has a new HC who was a former assistant on the team and a brand new PC. He was lucky and really likes both of them as well. But truthfully you never know.
Thank you for the perspective. You know it just might not be the right question I am asking then. I have seen the movement of coaches but don't think I put that in the overall perspective but that makes a ton of sense which goes back to keeping a good focus on the actual school and not just the baseball program. That is such a tough one with a kid who seems to have a one track mind.
