My installers came with 3 people and they were pretty efficient. One of the things they used were "S" hooks attached to tent stakes. They put the bottom track together, started the pool where the seam is inside an upright, put the wall into the bottom track and kept it upright with the "S" hooks and stakes. I don't remember how many they had (maybe 12 or more) but it kept the wall up as they did their thing. Also, I think they used duct tape to cover the screw heads to keep them from wearing the liner.

If you're talking totally by yourself I think it may be a bit much but with a few people, you should be OK.
