Stuck!!

I am stuck where you have to make a different show for a week without any mess ups for the Sultan. I have tried to switch only 1 or 2 of the performers a day. And I only put on 1 show a day, because I'm afraid if they are not rested that they will mess up. I believe that you must do an impression of 1300 or higher. By the end of the week, I am broke and usually someone messes up. I've been stuck for several months now, and I already started over several times because of different tasks, and I really don't want to start it over again. Anyone have any suggestions on how they past it?

what i did is save my game ones a day before the show and if some one meses up go to the saved game.hope i help.
