Sorry to hear that,
well depends where you are located. In the US you would need a license in order to dispatch aircraft. In Europe a license is (mostly) not required (country requirements), though having one or a formal course makes it a little easier.
Being a pilot you obviously already have the required knoweldge and would be eligible to obtain a FAA ticket with minimum effort (and cost).
As for the schools just check the threats, since they come up fairly frequently.
