Looking for a good paper that certificates a good workshop/ course / school for videographers. Any ideas?

What level are you talking about? There are a number of short courses/workshops for high end professionals.

Hi Brian, looking for something that can qualify this profession and could Give me The "addendum" for a selection....
I'm not a beginner! Thx
