Help needed to erect a wedding arbor

I need help putting up a wedding arbor, which is a 4-post temporary structure that a florist will decorate after we are done. It has a wood floor that needs to be assembled. I need someone who can carry wooden members up to 50 pounds, can handle basic power tools such as a battery-powered screw driver, and can work on a six-foot ladder. The location is the Kona Salt Farm, this Saturday, November 15th. You must arrive at 7:45 AM to begin. I pay $25/hr. It will be a half-day of work.
