The Per-Level Hunting Guide (link in my signature) recommends the Tesch Val Gnolls in South Karana or Splitpaw for Enchanters of your level. Other possibilities include Mistmoore at the castle entrance, the Festering Hag room in Unrest, and the walls outside Karnor's in Dreadlands.

And that's just the spots specifically recommended for Enchanters; if you take a look at the link there's plenty of other places that are likely also viable for Enchanters, just no one has specifically edited the guide to say as much.
