My pool took a couple days by hose, personally I wouldn't recommend with a well....but if there's no other options.
Try your fire department, if not then try contacting a local company that does road (re)construction or paving, locally the companies here have a bulk water agreement with our utilities commission that allows them to fill tankers from fire hydrants, these same companies will do pool fills. I think it's a bit of a loop hole in the agreement, but whatever.
