I think the mechanical advantage you’re looking for would have the rope anchored to the ceiling going through pulleys attached to the roof frame you built back up to the ceiling to new pulleys that feed towards where you’re going to secure it. Or something like that. Think pulley system on a cable machine
Maybe a come-along or the crank lever for boat trailers to crank the top up to the ceiling?

I think you're right, I might go grab a couple more pulleys and try to give it another go.
Also, Kermit lol!
Ye old harbor garbage sells an electric winch. You can plug into a regular 110 outlet. It might be an option for you.
