got a phone book....library...internet...check under commercial diving or diving, commercial. Ask your local diving school if they have a list. This is the job for a prospective diver to do...its not like we have lists on the wall. they come and go, in the last year or 2 I can think of half a dozen gone out of business. Some I wouldn't work for if I was starving.....which I'll never do anyway. This should be a mandatory project for everybody entering diving school- its called market research.
