GaryC - Still working on getting our test and insurance docs uploaded to the BVI gateway site. I've contacted them at their WhatsAp address and they are trying to help. Not resolved yet.

Regarding insurance - I was able to purchase the required insurance using the below link. Easy enough. Enter your specifics and you get quotes from a number of carriers.
