This question is based on a hypathetical situation, which may actually happen. The story is a high school production I know is currently rehearsing in hell week or one or two weeks prior(not quite sure don't quite know the whole scenario). I have been recently told that the guy who is mixing the show(an old friend) made a bad decision and will likely not be able to perform his job during the nites of the show b/c of discipline through the school. His fault at hand in my oppinion was not having a backup or someone that knows enough to fall back on in case of this scenario or something like it. Here is where the situation gets dicey, I have been approached to possibly step in last minute and learn the show in a week. Which, one I don't really have a problem with since I went to this high school and have high knowledge of the equipment. The hypathetical part is I have been commented to that I could be possibly paid for doing this last minute favor. The Q is how much would most high schools be willing to pay for a last minute gig in which a professional would stand in?
