Camps are often financial boons for schools to pay volunteer assistants etc but could, with the right coach and kid make a connection and prove to be an asset. I put my son in front of a few schools, one was private and the PC was consumed with what i did/did i make enough money and the other school like son and it showed out interest and willingness to attend (quite far from home). He probably got hundred of invites and i think that is more about email/spamming/fund raising that his abilities early on.
Best of luck to you, i'm sure more advice is following from the folks on the board.
