Bill in Dayton has pretty well described how I do it. The numbers are a bit different, but as Glenn says, you've got to know your market.

The highest demand night, by far, is Saturdays here, so I tend not to be as flexible in pricing on that night. But, for any new venue, before giving a price I like to find out what socio-economic category they fit into and how many guests will be at the event.

High volume clients' requests deserve serious consideration if it looks like the gig could be lost otherwise.
