I'm past the elementary PTO stage myself, but involved in various parent group activities in middle school and high school. So I still find the PTO Today resources and interactions extremely valuable.
Sorry no theatre publications, so I can't help there. But I wish you luck!
I'm baa-ack - but now involved at the High School music boosters (theatre) level with my sophomore!
Our musical this year is Oliver! (Food, Glorious Food! and Consider yourself!)
....and in the past we have sold ad space in the theatre program. (i.e. business card size is $40 bucks, 1/2 page is $XX, back cover is $XXX).
Our past theatre coordinator was "asked to leave" and took all of the past advertising files with her! So now we're scrambling.
If anyone has a mock up from a show with ad rates, the "begging letters" and timing, would greatly appreciate a .pdf copy of your notes. We open March 15th!
