Maybe a community member will read your posting... But you can try social media to find somebody in your region. Or look for other hosts in the neighbourhood of your listing, maybe somebody will help you out. I noticed 4 other hosts are nearby your listing on Russell Island. Most close are "bleu dolphin cottage" and "Boo's bungalow".
some one close to you, or you have trust. Your co- host should have knowledge about hosting, at least have some experience with the program. Some one who won’t let you down. Quick to respond within reasonable time.
