found a 12'Wx35'Lx30'T for $40/month! with electricity, lights and a/c!

cant wait to get it in there so i can really get to work! ill get some pics up of her in the new home soon, gotta clean and build a bench before i put her in there.
So question would be... what is a good strength winch to use for a hoist/lift? i dont want to spend alot of $$ on the winch, just building the rails and brackets is going to cost enough. i want to be able to lift a motor, and would love to be able to lift the body off if possible. any suggestions?
thanks
