Some are honest and mean no harm. Others seek to take advantage of you. Their goal may be income, improper help with school projects, prestige (look what I did except you did it not them), who knows but they smell of fraud or deception.
I see two structures needed. The creative and the procedural. The procedural is what Musashidan wrote of and including a command hierarchy. The creative one is the imaginative part, story, characters, style. This brings imagination and production together to accomplish the goal.
The only experience I have:

The creative structure was not in place. I expected everyone to participate in continuing development of the imaginative part but that is not everyone’s talent.
