Diving Requirements

Requirements for a career in diving.?
An instructor or guide. Can anyone give me a rough idea on the cost / time / number of dives / Age / education requirements that I know little of what the job actually involves. I am 17 and have done 41 dives in total, and I'm thinking of becoming an instructor, but the cost seems a bit afraid because, for the moment, the pockets are pretty empty. I also think he needs more experience before he can seek the license, age and more dives. Any advice / answers are appreciated, thanks.

The courses are taught by instructor trainers or course directors. Cost of the courses varies between $ 1,000.00 or more. Some stores offer payment plans or will direct to legal aid. I've known people to get assistance through the VA and have seen with American Indians / Alaska Natives subsidies education of the tribe. The prices are controlled by Scuba training facilities that offer the courses. There are many certification bodies out there and I would compare them to ensure they can meet their needs. My original dive instructor course eons ago through PADI and ran 12 days. Minimum is AGAE 18 for all agencies and certifyings think most require a minimum number of logged dives prior to entry and a minimum number of dives registered before being certified as an instructor. I remember that 60 dives as entry requirements and 100 dives as an exit requirement. Upon certification Instructor liability insurance is required prior to actually accept and train students. I am currently in my 25 years of teaching and (wood hit) have bemoaned as a career.
