$1000 would be my charge roughly (probably more like 100 per hour, but there aint that option. Part of it is working conditions and the expectation....8 hrs with a 30 minute break can be a little rough on the body...I think this is also reasonable given the expectation of a setup for award winners plus candid/event coverage. If it was for something I thought to be a worthwhile cause (IE a sporting competition in which I was involved or associated) I might drop it to 500-600 as a sort of contribution to that event.
