diy Uplighting and Pipe and Drape

I am having my reception and ceremony in the same venue. While the reception space is lovely, the ceremony room is not cute. It's a room for meetings with yellow walls and pictures that the venue refuse to move for the ceremony. I had an idea for pipe and drape to cover the walls. I got a quote to DIY pipe and drape the room myself for a third of the price that the venue is charging. I was thinking about utilizing the wedding party to help install and take it down. Do you think that it's too much to ask of them to do? How long will it take to pipe and drape a room that 30 ft. x 30 ft.? Disregard uplighting inquiry.
