ONE MORE TIME:

There is a real difference between DJ's who do their own management,
and DJ Booking offices... DJ Booking offices have a more commercial additude...

Mark's comments only make sence when the DJ does his own management. But when you're a part of a booking list of some big agent,
you can't decide about variation in pricing your fee....

So if you want to book a big act,
you just have to accept what the agent is asking. Period!
