I've seen it done in 10 mins but i'm sure you'll get charged for more labour than that!
It depends what you want done, do you want OEM settings or it changed? There are many places that do geometry (HiQ etc.) but know nothing about adjusting it from standard...Anyway, i would avoid anywhere that uses machines. Twice i've been to places and they've been way out. Badly calibrated i guess. You can't beat two pieces of fishing line!
But basically any motorsport outfit should be able to do it...
