Holiday Party Help

We're looking for someone to help with our holiday party on the evening of Saturday, December 3, 7:30p - midnight. Expecting about 50 guests over the course of the evening, and we'd like help just before the party starts getting things ready (setting up food and drinks, etc.), during the party (refilling food plates, pouring wine and other drinks, clearing glasses, loading the dishwasher and some cleanup, etc.). We're looking for someone who is reliable, cheerful, proactive, friendly, and responsible, with prior experience doing similar work.
