Where to Hire a "Gun Wrangler"

While idly Googling around I came across a Canadian company that is set up to provide rentals and services to film and TV production companies. A&A Airsoft is willing rent weapons, equipment and the trained soldiers to operate it all along of with the services of a gun wrangler. From this company's name it probably started off selling Airsoft guns and then branched out into equipment and services and military surplus. The one book they sell, Once Upon a Wartime: A Canadian Who Survived the Devil's Brigade, is a memoir from a member of the Devil's brigade with a custom inscription from the author.
