I found private testing in our neighborhood for $50, with 24-48 hour turnaround. However, it takes us 20 hours to get to the BVI. It's not clear how we will be able to pick up the results, upload them and make our flight, assuming we test negative.

From what I have read, the final test in the BVI is to be done four full days after arrival. So if you arrive Monday evening, you would be retested Friday evening. Not sure if you have to wait for negative results to move about, but it would make sense. So that would mean Saturday before you are clear.

The rules I saw posted also said boaters must stay within 30 feet of their boat, so no windsurfing or kayaking, it appears. There was mention of certain attractions which might be visited, so perhaps some remote beaches. We will see. Obviously people can't quarantine in populated areas.
