Suggestions-- Contact the Military Science program at SFA. Some of the students and even staff/faculty there may be interested in participating with you folks. They once maintained a .22 range located underneath the SFA coliseum, but closed it due to lead issues a number of yrs back.
Perhaps Angelina College may have an ROTC program as well.
Target the SFA and AC faculty/staff. I knew of a number of my colleagues at SFA that had an interest in firearms. You could place a small ad in the campus newspapers and see if that generates some interest.
I'm an ex-Nacogdochian (77-94).
I've been meaning to come out that way and catch you folks sometime. Drop me a note about your 15th meeting. I"d enjoy coming out if I can get away.
