For example, a photographer can have an undisclosed rate of $300 an hour, but still able to charge as high as $10k for a whole wedding. This also ensures that you sell your albums as well because it's part of the 'package'.
For myself, I find it so much easier to charge a lot higher now with packages or total solutions, vs breaking it down into rates. And the best part is, I don't bang my head on the wall when i could have made twice as much if someone with a 12-hour job tries to book you on the day when you've already been booked for a 6-hour job.
Just my $0.02
