There are quite a few driver training schools around that provide pro drivers and plenty of track time. I've done a John Bowe high performance trackday before and I would highly recommend them. Heaps of pro drivers there (inc John Bowe) and a full day with as much track time as you want (usually a few nice cars too!!). Think I got about 40 laps in that day taking it pretty easy. Cost was around the $450 mark for the day.
