I didn't see u/w as a venue option...
You might try contacting Tim - kidspot - he's a childrens minister on Oahu as well as a dive instructor. He might have a colleague who dives on the big island.
Sorry, I don't know anyone over there either ... I've considered ordination, and been offered a couple of times in the past, just never seemed to be the right path at that point in life... perhaps one day.
Aloha, Tim
