We prefer state parks so we just looked at the area we wanted to try the workamping life, called the state park we wanted and asked for the volunteer coordinator. We had a resume prepared highlighting what we had to offer for the state park environment and never needed to give to anyone. The coordinator told us what was needed (filling out a simple application for the background check) and we were off and running.
We continue to get gigs by just calling the park that looks interesting and going from there. Works for us.
P.S. We are both Navy retired living the good life.
