I would do a short video and post it on you tube. See how many hits you get and go from there. I watched Kelly redo her 54' on there and there are several people using it to market longer versions of how to videos. At least people can see the quality of your video and your work. I have rented several how to videos from smartflix.com the latest was on changing the ring and pinion on a GM 10 bolt rear end. That is another good outlet for videos on any subject. Your skill level would determine if I would purchase the video or not. I am good to go if I can learn something new.
