Hi Damien! My opinion is if you your sponsor and co-sponsor does not help enough, you can always find a mentor among A2A friends who are already doing this job longer. I think everyone is willing to help you if you need to explain something. And there is a forum where each issue gets more responses. If that does not help you can contact the 24 - hour support or directly ask Gary. All will help, just need to ask!
I wish you success in your work!
