Kreeft charges $2000 per day or part of a day away from home (plus plane fare) and is available Friday thru Sunday on some weekends. (This is very reasonable given his profile and schedule—he charges mostly for time away from family.)
Please include his website on all promotional material http://www.peterkreeft.com and send us an audio or video of the talk.
When you have a few candidate dates and topics, you may be put in touch with Dr. Kreeft. (Note that he will do topics he's previously covered, but prefers to do new, subject-specific ones. For a list of common previous topics already addressed see Featured Audio.)
