I need money, whats a profitable trade?

Mage, druid, necro and shaman are all pretty easy to solo with classes, and with each them of them around level 30 you can farm up quite a bit of money. A lot of players including myself leveled/farmed the Misty Thicket guards, great exp and 10pp per kill from the spears they drop. I know 2 players who have farmed up to like 30k from those guards.
