Howdy!
I was certified in High School, and in my last year was the president of our scuba club.
Best bet is to talk to an LDS and set up a course or something for students in the club (that way it's not exclusive to only certified divers, get more people into it who might not do it otherwise...). Maybe organize a trip with the LDS to somewhere with good diving.
For example, we did all the classroom and pool work in Edmonton over weekends during the school year, and then went on a week long trip to Vancouver over spring break. There we did our open water certification dives early in the week, and organized dives for the rest of the week. It was all on a live-aboard. Already certified divers were welcome on the trip as well.
The LDS got us a good deal on this charter/course/rentals and we all had a blast!
