Hire a door man

Hello, I am looking for a door man for an event. They would be responsible for making sure no one takes drinks outside the event and possibly asking people to sign a guest book. No bouncing, no guest list or anything like that. Event will be in November 17th in Yaletown, Vancouver. Expect the event to be about 4 hours, with a chance of running 2-3 hours longer (still confirming). Will pay $100 for the first 4 hours and we can discuss about the rest.
