Event usher for classical music concert

I am in need of an event usher for two back to back classical music concerts. The day will last 7.5 hours (2pm - 9:30pm) with a flat rate of $200. The dress code for the event is formal attire, which requires black shoes, black pants, and a long sleeve plain black shirt. The usher will be required to not only scan tickets, but also hand out programs and assist with setting up and packing up chairs. Therefore, it is essential for the ideal candidate to have experience in customer service and be able to multitask effectively. The successful candidate should be friendly, approachable, and able to work well under pressure.
