So your task will be the following:
You will have to create videos for several topics (not sure about the topics yet) with a solid video quality.
The video doesn't have to be that perfect, but it should contain good content as far as the topic goes.
You can either create videos with a quality video camera, or just use screencastsoftware, depending in what is needed.
So you could probably have to create a "how-to"-video tutorial for instance something like "5 training exercises on how to lose fat fast" (I will deliver the content so you can focus on the video itself)
another example could be that you have to create simple "lets-play"-videos, where you play basically just play a modern game, screencasting it and doing a voiceover.
All the content you create has to go with the youtube partnership guidelines (no copyright infringement etc.)
