Experience and Crew Required for Chartering
From what you write, it seems to me that you should have no troubles. Handling the boat is only one aspect of skippering. If your judgment is sound, and you have even mediocre navigational skills, the BVIs are usually a pretty easy cruising ground.
If your chartering crewman is a good learner, then so much the better. My advice when you go is to just take it slow and easy with all your maneuvering (anchoring, mooring pickup, docking) and put your training to work.
Have a great time!
