personaldivers.com  are a personal dive company.  We went diving with them and they were great.  The picked us up at our hotel and took us back to their house to practice in their pool. Then they took us out to the ocean and we went scuba diving.  We went diving once before with a bigger company, and they had us on a boat with like 30 other people and it was bad.  With personal divers it was us 2 and the divers.  The cost was less with personal divers too.  The are very friendly and experienced.  We went 2x while on our trip with them.
