sorry can't help you - but appropos How does one go about starting a competition? is it worth having on eof it won;t get built- just competition - i would like to do that.
i guess i would need some judges that were respected enough to make people want to be judged by them , and some sponsors that would shell out $, big ones i think would be better, they won't notice the money. what else- adversiting? i could do it all online maybe? suggestions? interest?

try these.

for some of the posts you need to be a registered architect and do the RFP thing, but are enough open competitions to interest students and young graduates.
