Hi Sam,
Great idea and good luck with your STOL competition.
I do hope there will be a webcam focused on the area of landing , and you could promote it via facebook live streaming.
You mentioned ideas for prizes , and as a printer I see more and more of these wood photo's being asked for

so a photo or logo of your STOL competition laser etched on a bit of wood , looks surprisingly good and it is quite cheap to produce.
hth,
