Hat steaming/reshaping?

[desiringsubject.livejournal.com]

I have two nice hats, both fedora-esque (one pictured in the icon) that through moves and general lack of attention are dusty, misshapen and abused. I would like to get them steamed into shape and cleaned properly. Does anyone have a recommendation? I don't know if this is an obvious thing that drycleaners do, or I need to find some kind of haberdasher?

Thanks!
