If you can spare the expense (and if there is still availability), the Stanford camp is exceptional. I have attached a list of schools that are attending/coaching. It's $1,100 but an awesome experience and my son made a lot of contact with coaches during that camp: http://www.stanfordbaseballcam...HS_Aged_Players_.htm
We also found that HeadFirst provided the most focused time to communicate directly with coaches so I recommend that camp as well. Good luck!
