I probably wont be much help on getting a structure up since mine was built by two guys that are apparently too swamped to take any more work on, plus its too far out of their area.
However, I will be happy to help answer any questions etc if you have them.
As far as time frame I’d like to do it as soon as the snow is gone, as with the few contractors I’ve spoken with said it “was” possible to construct in the winter months, the cost was greater.
