What city are you in? In Freeport and Qeynos they're *right* outside the Tradeskill instances, except The Coalition of Tradesfilke and the Ironforge Exchange. In Neriak and Kelethin they're near the main crafting areas, um... the Down Under and Jolena's Restaurant, if memory serves. They have a tag under their name that says Crafting Trainer.
They're the same ones the sell your books, or who made you Artisan if you didn't do it on the newb Isle.
