Certs for 4x4 are you kidding me, it's about time, skill, practice and who knows just being smart about how you drive. Unless you won some kinda trophy or something who cares remember it's about what you do have to offer and that is an unending commitment to the promotion of the FJ and safe driving. Keep in mind that most of the guys who would want to do this are restrained by a dog, job, or family in that order. You on the other hand will show up to work on Monday fire your boss and be on the road the same day. Think about it who has the time to do this, exactly retired guys, and who in their 20's is going to take a bunch of safety guff from guys their dad's age no offense to older people. You on the other hand can speak their language and translate to the X and Y gens.
