Asking for the imposable.
All decking has trade offs.
Pressure treated pine is the cheapest, easy to install but the highest mantaince.
Composite decking will cost three times as much if not more then pine.
Woods like IPE are very low mantaince but need to be predrilled there so dense so it's slower to install but you end up with a deck that's real wood and should last at least a life time.
