Easy enough to do on your own. Make a cardboard template, tape it to the rotor and use an automatic center punch to mark hole position. Get the proper bit for the job (cobalt are very nice) and with the right speeds/feeds and plenty of oil, you should be able to drill all the holes you could want with one bit. I did a set of rotors before they were thinned years ago with a $3 TiN coated bit from Lowe's. If you don't have a drill press then you will have to cough up the money to have it done, otherwise, its pretty easy. Having a helper to oil is certainly nice though.
