Go to the school websites and email the coaches. Also, pick out the schools you are interested in and go to those camps. They can not CALL YOU until July 1 before your senior year.
I used to work at the LSU camp. If I had a kid I thought they "needed to see," I would call one of their coaches over. Just speaking on my experiences at LSU, but that is how they get a better look at the kids they are interested in. Even a few that were not on their radar, got on that radar and were signed by going to their camps.
