Dailies at Quel'danas. In the middle of shattrat there are a few portals, 1 corner for horde, 1 for alliance and one with a dreanei standing in front of a portal leading to the Isle of Quel'danas. Go there, pickup all the dailies, read the questlogs and farm some nice money. The dailies really are simple. Check wowhead comments if needed.

Do some instances just for fun
