Getting good! I do most builds with the frame ratchet-strapped to a furniture dolly (usually with doubled 2x4s to raise it up). When mounting the wheels, do one with the bike tipped over (forward or backward) just a bit then put it balanced on the center stand to mount the other (with a floor jack keeping the unmounted end up). Every bike that I've done this on so far has had the center stand at a balance point so that removing a wheel will tip it in that direction. Just put a floor jack or jack stand under that end. Without the center stand you just have to be a bit more clever.
