If there are no leaks in the suction line your pump should be able to pump water to 25' reguardless of the well depth. I'd suggest that you start again with a new hole. Wash a 2" PVC pipe down until you get clean sand returning around the 2" pipe. Then install your sand point and 1-1/4" pipe into the 2" pipe until you feel that you have hit clay or something hard. Then I suggest that you install a shallow well hand pump (pitcher pump) and see if you can pump water, if you can install your jet pump. Or you can run a small air hose in the 1-1/4" pipe and connect the air line to an air compressor (like blowing on a straw in a glass of water). By blowing you can develop the well and test for gallons per minute.
