Producing Revit training videos?

I have a small question. We are a firm specializing in training for arhictectural firms. Up until now, we sent our instructors to our client.

We are currently looking in producing videos. The question is: What exactly do you need in terms of license?

Ex: If a private person has this license in his name. Can we hire him to produce these videos for us and then distribute them as we please. Or do we need a license too.

Ex2: If we need this person also to produce files and examples. We do not need to open them, not modify.

Essentially can we want to outsource video production.
