Ask lots of questions of the organization exactly what is and is not included before signing on. Try, also, to get a good idea of what schools are typically at the events they will be playing. See if this matches up with your son's target schools. Ask things like how much training/facility time is included, if any. While there is cost to uniforms, etc., the value is in how much better he will get and who will see him, as well as how strong the connections are within the organization and targeted schools.
