If your not tearing down/putting up walls, changing electrical or pluming (behind walls).
It does not sound like you need a general contractor,
I can lay wood flooring (about one room a day, took me about one day trial and error messing it up a few times to figure it out).
I think you could find specially people to do each one of the others just shop around a little first, don’t just take the first bid, (very important) don’t pay them except materials, ask for receipts as well, until the job is done, watch them like a hawk.
