First of all tune your hearth stone into an area that has a horde/alliance auction house. Then fly to Gadgetzan, Tanaris then fly to Cenarion Hold. Then walk to the back of Un'Goro Crater.
There you can do two things, either farm for Rugged Leather off all the beasts there.
Or my favorite the Devilsaur-with the Devilsaur you can sell here skin in stacks of 10 and make a large sum of money.
Usually I can sell a stack of 10 for about 30-40g and it takes me an hour to an hour and a half.

The best run I have had I got the Fiery Enchant (35g), and the Ace of Elementals (300g+) for about 10 minutes time in the instance. Those prices are on my server.

My main is a rogue so this is written from a rogue point of view, but maybe you could do it with a druid?

Follow the steps to solo Plugger for the Barman Shanker.

Tired of Tyr's Hand? Want to do something Chinese Farmers can't do? Try solo bosses in DM East. You do need (dis)enchanting to be able to make the most of it, but read on.

Resetting an instance:

Invite someone to your party, leave party, log out during the countdown to Iron Forge and log back in, you will not only reset the instance but also be teleported back to the start of the instance.
