Here, it'd take 2 guys about 3 - 4 days tops, to rip off (not save) old sideing and place new on and trim out all those windows/door (assuming he'll wrap all the windows and doors with metal)  . . . .
That's a lot of windows for such a small home . . . .
That's here and they'd be working at least 8hrs and generally 10 hrs, as they have other homes to move on too.
