The 3 at the shadowvault are easy and quick to do. Harpoon, Kill 3 guys and plant flags. Burn down the building next to the drake 8 times. About 40g per toon.

I skip the saronite miners as its annoying that 2/3 of them either attack you or suicide into the back of the cave.

The pvp dailies in Grizzly Hills are quick and easy to do.
