I think they do in fact owe us some Grade A content, seeing how the "ESO plus" is supposed to include the extra expansions to the game for free, but by the time the release those the cost of ESO plus will heavily outweigh the cost of the expansion, I am sure. Not that I really mind, I just want them to update the game because it is super boring doing the same stuff over and over..
I think some of us have just started talking about our own thing @Psychobunni.
Maybe OP is thinking of trying to organize a Quest Guild with players playing NPCs and giving out quest info and whatnot. I've considered this type of thing but I don't think players should be trying to provide content that ZOS is unwilling to and unwilling to support.
Give us the Creation tools and watch the magic happen.
Maybe the op is thinking of charging for this "service".... I really don't think they will have much luck with that. I'm not even sure it would be within the TOS.
