Backwards Bee Keepers might remove your hive themselves (if a member needs a brood) or, if not, then they have a list of companies that do live removal for a fee. I've always liked the idea of a back yard beehive. I recommend exploring their web site for more information. Nice.
(moments later) Oh wait. It looks like they are defunct. Still, there seems to be some useful links and contacts there. For example, http://honeylove.org/rescuebees/
