Yep a simple way to go is Harbor Freight has a 1HP Stainless Steel Shallow Well Pump and Tank with Pressure Control Switch-950 GPH for $179. 1" inlet and outlet ports,30PSI On/ 50PSI off. Just put that on top poly tank, mounted on a nice plywood/2x4 , base and Tee into ur system. Can just add a butterfly valve so ur existing well pressure tank is out of the game. Shut off the big well pump breaker, til you start using it again. Ya won't be able to tell the difference from normal.
