This hits the nail on the head.
It's a pretty common discussion on photography-on-the.net, not necessarily with cosplay shoots but with models of all types. Charging for your shoot - even a little bit - will place a value on it, and weed out some of the people that aren't serious. Taking advance deposits will all but eliminate your flakes.
