Do Meriana Quest in Liberty Bay to get access to Nargor. Once you finish the quest, you can do pirate tasks (killing 3000 of them, you can do it more than one time, and once you finish, you can kill the boss that always drop a pricey item).
Hunting pirates do great XP at your level range, and also drop a lot of items used for addon that worth 3k+ each.
I always made cash there, something like 20~40k in 25~40minutes.
Good luck!
