Drilling new rotor holes for Scarebird

I am considering staying with my sbp and converting to front disks and am looking at the Scarebird system. I see where folks have drilled the rotors for the sbp for the Scarebird brake conversions, but I have not heard how they are doing it, other than a few have taken theirs to a machine shop. On the Scarebird website they say they give you a paper template to do your own drilling. I have access to a floor drill press, but still think my drilling accuracy would be marginal and the bolt circle would not be perfectly centered. Somehow this seems like it could cause vibration problems?

Would your basic auto machine shop have some more accurate tooling or templates to do a better job?
