Hypnotist Show

I am wondering why it seems that the popular white colleges hire me and I have had no responses fromt the HBCU! This is a very good money maker for a school or an individual. I have had 15 bookings from the white colleges but I am wondering whats going on here. I can only extend a hand but can't make people grip it. The white colleges are using the money from the show which is anything from $5000-$10000 after expenses to do the things that need to be done.
