check out the site and leme know what your looking for. we also are the provider of all the wood sheds you see at Lowe's as well, any of those are DIY or installed. ill see what kinda price i can get for you if you do it through my branch location. our DIY is great. everything is pre cut, pre hung doors, preprimed siding, ready to paid. full picture instructions. more or less, putting a big puzzle together. you wouldnt need to cut anything except maybe flooring depending on what you choose.
you can do a slab if you want, gonna last the longest. your gonna want at least 3/4" treated flooring if your putting a tractor/snow plow setup in there. OSB cheap flooring will rot and get soggy from the snow and shit. check with your town codes. some require that you HAVE to have a slab. most dont though. some just require you have a 50$ permit paid and displayed the day of your build.
contact me and ill help you. let me know what town your in, i can look up all the requirement at work in the file for that town for you as well.
