Powerpoint & Excel "boot camp"

I was wondering if anyone had insight into a reputable and applicable group that performed training sessions for Excel & Powerpoint.

Specifically, advanced training that would be done in several days, not so much weeks. Thinking of the same type of training you would get in an analyst training program, specific to IB and Accounting, NOT looking for a Wall Street Prep type class, more hands on.

We are bringing on a few analysts in with limited software experience and was hoping to get them up speed asap. Geographic market is Philadelphia, so location is essential.
