I was first going to make a joking comment about being asked to help and then thought perhaps the owner has physical limitations and thought better of it.
My suggestion is to do it "assembly line style" - install all the levelers on the legs, then put the cams in the I-Beams and then posts/dowels in the legs and just connect and close the cams. I've helped a friend in the past and the instructions are color coded and it went fast.
