If you decide you want to DIY you're welcome to borrow this man lift. Not motorized so you have to push around but it sure makes getting up and down easy. 12ft platform height. Installation shouldn't be that hard if you have something suitable to drive the self-drilling/tapping screws. Biggest thing is getting that first sheet square so the rest ends up right. Did insulation come with the package? Seems odd but without it condensation will form and drip on the underside.
