OK, I just reread this and am thoroughly lost. If you have certified instructors from an existing agency, why not just use that agency's materials and certifications? Is there something wrong with getting people certified through an existing agency? What is the benefit of using the experienced diver program? The existing agencies' prices are not your concern--you control it. If you are a nonprofit, you should be able to offer an existing agency's certification at whatever price you want.Our first supported diver was a challenged Iraq vet paralyzed from the waist down. Liability is no more of an issue for us than anyone else, and we are insured. We have certified instructors from two of the major organizations but we are not going to use their material, name or anything connected to them. The exception would be to offer an experienced diver course and let them cross over to whatever agency they choose if they wanted to spend the extra money.
