I would try targeting some schools that your son may be interested in and see if they have a camp this fall.
The Clemson Camp in December is AWESOME! There are a ton of kids there, but that means a ton of coaches to work them out. My son attended last year and I believe I counted 23 additonal schools present other than Clemson. We got some pretty good contacts from it. Also your son will get REPS like no other. They kids never stop moving while the camp is going on.
