See the article Tradeskill Timeline for a progressional series of tradeskill quests.

There are a variety of Tradeskill quests which reward you with tradeskill experience, faction, advanced recipe books, and specialist tradeskill cloaks. All tradeskilling quests can be performed by low level adventurers, although they do require visiting progressively higher level (and more dangerous) zones. Invisibility or Stealth and/or grouping with a group of high level adventurers is recommended.
