I wish I lived in Tampa Bay to take you. (sorry, I’m on the other coast) But I would suggest either doing a search on this site for divers in that area and reaching out direct to them via messages (not everyone checks this board every day), or just sign up for a charter when you are there and meet new people on the boat. No doubt the DM on the boat will take you under his/her wing at the minimum. If it’s your first time diving in the ocean it would be advisable to make your first dive under supervision. Perhaps you could contact the local dive shops in Tampa and ask if they would schedule a guided tour like many tropical resorts do? Stay wet!!
