In every successful industry you'll see scammers pop up. I've also seen those videos and usually at the end of it they'll try to sell you on their course, private membership forum, or something like that.

That said, even for projects that you do as a calling, I still believe you should charge a lot, simply to make others and especially business types respect you.
