Rotors are about $200 each, I think, can't remember the last quote. Machining should be around $50-70. I'm not sure about redrilling. You'll also need pads if you don't already have any.
The problem is finding someone to do it for you, I asked about 7 different brake places, all of which told me that they don't do that. Finally found a guy and he stuffed them. Find an engineering place, they'll be your best bet as brake places don't seem to want to touch them.
