It will lift about 6" and the rear wheel can slip out easy, just getting it back in may present its own problems, but a wedge of wood may work wonders. It pulls the bike to upright from the sidestand with no real effort on the handle.
As for going public....bearing in mind it is heavy and the handle is 4ft long, let alone the day to make it, don't mind anyone copying the design and would happily supply measurements.
Anyone who is handy with an angle grinder and a welder will have no problems as it is very basic......just very heavy.
Will have to post some pics of it in use as may help.
