I did a program like this one. Mermaids was one I reasearcher, but it is too far from me. These programs are a lot of work in a very short time. You will get a lot of criticism, like the "Zero to Hero" comment. While it is true that dive instructors dont make a ton of money, it is still a very fufilling job. If you want to get to the professional level and cant afford to take a few years doing it, this is a great way to go. I loved the program I was in and ended up geting a great job less than a week later. As I said, it is a lot of work. I recommend geting a copy of the Recreational Encyclopedia of Diving Manual now and start learning as much as possible. If you commit to the program they can make a wonderful new career for you. Good luck with whatever choice you end up making. If you have any questions, feel free to contact me.
