If you have the money to spend then a Haas office mill is perfect for this. It is 12x12x10. The 2a model has 20 pocket tool changer. 30k rpm and a self contained coolant system. I am pretty sure they have a rotary available for them and they can roll through a 36" door. They also run on 220 single phase. We have one at work and I enjoy cutting on it. It runs fast, like 720ipm rapids and 500ipm cut speeds. If you get the loaded one I believe it is like 50k or somthing like that. I am not sure if you are looking to spend that much but it is a real deal machine.
