If the club coach does not want to be too involved it is possible to get another coach/advisor involved (at your request). When I say advisor I do not mean a college recruiting advisor like CAA or one of many others out there. If your kid is as elite schools will find you. It could be his HS coach or pitching lesson coach or a friend of the family (be careful with that one as you would want the coach to be able to ask the right questions and not be ignorant to things he should know).
I say this because it might be nice to have a middle man of sorts to be the good/bad guy with coaches who is an advocate for your son and he'd be able to ask the tough questions of schools that are interested and potentially be someone that reaches out to schools on his behalf. (That was an incredible sentence but don't want to try to redo it). I hope that makes sense.
