If you want to level fast I'd go with Malkindred's suggestion and head to Paludal Caverns.
On the other hand if you're looking to level a bit more slowly and make a bunch of plat then try the Karana's and do the pelt faming route. Kill lions, tigers, wolves, spiders, etc or whatever critters drop the trade skill components. Collect a few bags full of the stuff then set up your bazaar trader overnight. Come back the next day with a bunch of plat then head back to the Karana's.
