I was a certified instructor for many years, but I needed to make a Re-Certifiecation process for teaching the newest version of Cinema 4D. It takes a couple of weeks,.. but worth it! If you want to be a tutor, just go ahead! You can be a part of a good team, and you can give your 3D knowledge to someone else. What is this knowledge?! Cinema 4D is one of the best 3D platforms I've ever used. Why?! It's easy to learn, It's easy to use,.. and the results are amazing! Just try it! 

Good luck for the first dating with Cinema 4D!
