I am and have been on both sides of the fence. I have been a 'social' instructor for more than 20 years now and had to learn things the hard way. Honestly, I was too embarrassed to ask what you did. If you put yourself in a position to call yourself an instructor, be prepared to back it up. Even if you are doing this as a hobby, bobbies are just as costly. Maybe you can get your students to donate $ for the materials necessary for you to teach properly. I have to agree that the DV syllabus is the best way to go. Don't make the same mistakes I have and think it doesn't matter as long as people are coming. Just remember that every day is a new opportunity for learning (not just steps).
Invest in your learning materials and you will be respected for it.
