Well, this place has been left pretty empty so I have decided to post the way I used to solo ZG on my hunter. I am not sure of the prices anymore on voodoo dolls but I imagine you can still make some money off em. Click http://www.warcraftmovies.com/stream.php?id=28727 to see the video.
I found this REALLY fun to do, not only do you get the chance to get a lot of money, but you also learn how to dodge mobs extremely effectively. If for nothing else this is good for getting a nice ZG pet or maybe getting some rep killing some solo mobs. This can also be done by rogues if you have another rogue friend with you, and basicly have your rogue friend do what the hunter has his pet do then vanish at the end.
Edit: I was tired when i wrote this, so i forgot to add the I didn't make the movie, I just like using it. Very detailed and helpful.
