Make sure you check pre requisites with your local club. When I started doing track days the local PCA and other clubs required you take their one day drivers school or another sanctioned school before you could sign up for a DE event.
Our track has a "resident" racing school (Proformance) and their one day course for performance driving is about $500. The PCA driver school was less than $100. The main difference was the performance school done by Proformance Racing included half a day of lapping with an instructor. The PCA day included some autocross but no lapping. I've since also done the PCA school.
Careful, it's addicting. 5 years later I'm racing vintage.
