Call your local hospital's education and development department or even human resources and they should be able to direct you and tell you the cost. If you work in a hospital - contact one of the ICU's, or ER. Good luck - its a fun and interesting class.
I just took the class; it was great! Make sure you purchase the little Algorhythm Book for $ 10 in addition to the ACLS AH Book. The little book has flow charts that help tremendously in your megacode.
Good luck! It's a great skill and an informative class.
