I have a mod that I feel is pretty darn good:
http://skyrim.nexusmods.com/downloads/file.php?id=8429
However, as of now, it is lacking in quests, mostly because I can't script, and my modding skills are limited to placing NPCs and dialogue. I recruited one modder, Roarian, and he did a fantastic job with the quests we have, but he is very busy, just one person, and has had trouble with scenes and removing double voices from followers and such.
One of the commenters recommended I put a post here, and see if I can possibly recruit more people on to the project. The quest we are currently having trouble implementing is outlined on the files page, and may serve as an audition of sorts.
