Best dive operator- Turks and Caicos ( Provo)

Hi, my fiance and I are heading to Turks and Caicos mid December and are looking to do several dives while we are there! We don't want to dive with a cattle type company and rather a smaller operation that can take us to some of the better un crowded areas. We are both advanced divers with over 80 dives each.
Does anyone have any dive operator suggestions for Provo? We are staying in Grace Bay.
Thanks in advance:)
