There may be a forge in your area that you can rent time at. Here's a place on the edge of Boston that offers both classes and an "open smithy" for working on your own stuff: http://www.prospecthillforge.com/ (if nothing else, click for the nostalgic Web 1.0 design)
Went to this place a few months ago taking one of the intro classes, the guy that ran the class is super nice and has a very fun teaching style. You man the forges in pairs so it's a good idea to take the class with a friend.
