In Need

I've been searching a way to purchase flashlights in bulk and its not going so well. Does anyone have any suggestions? Ideally, I would like to have at least 100 flashlights and I need ones that are fairly powerful and could stand upright if set down on the handle end. I thought about asking around or sending out some emails about borrowing or having people donate them, but who is really going to lend someone their flashlight for 9 months? What if the power goes out?
