Only asking as all the summer/camp jobs will be full by now, if not within a couple of weeks or so.
But can point you in the right direction depending what he wants to do.
Has he got any interest in coaching football to kids in summer camps does he want a general volunteer camp job?
I've got a few mates that have done it.
Went through Camp America and worked as Football and General Sports Coaches.
Crap pay but it's all about the experience.
