You can pay extra to get the same school that the M5/M6 owners receive. Since you're in SC, I would certainly take PC delivery.
As far as the track time, check with your local BMW CCA chapter, I'm sure they have a driver's school that will cost $400-500 for an entire weekend of track time. I much better bargain, and you get a dedicated instructor for the entire weekend.
Here's video of a few laps at a BMW CCA driver's school, in this case it's at Summit Point in WV.
