I do hope you get some more current suggestions than mine, so I can learn in case I have a need as well.
My purchase turned out better than normal for a "cheap man that spends the most". (We were saving for college x4 budgets.) Pre-built MORGAN sheds on East side of HWY6 freeway near Bryan in-the-day, the year 1995 ... and is as good as new as was then (if washed).

Portable Building Outlet HWY 6 Bryan
Morgan Dutch Barn 10x12' V9TACSAN H-1
Front door, rear SH window, treated floor
Delivered & leveled above ground
$1834.84
Added treated floor, anticipating kids would leave the door open in rain.
ABOVE grade important, another one built by a kid floods, ants, etc.
All METAL exterior = NO work, except clearing fallen branches, washing every few years
Pest deterrents for underneath include all sorts of powders, sprays, even Irish Spring if you have no dogs to patrol it
Power? I bought a ground-rot resistant high amp extension cord and shallow buried it, Presto! Let there be light, charging, even small power tools.
They will handle permits & clearances to property lines, if any legals afoot.
2016 my last inquiry resulted in a pretty good price w/many options
