Anybody know anything about pulling wells?

The water pressure was real low, so we were going to pull the well and put in new pipe and a point. A neighbor knew how to do it, so we traded a kitchen stove for his labor and expertise(we got screwed). Tried using his jack(kind of a high lift unit)and some chain and couldn't get the pipe to budge. Another neighbor came over and tried using hydraulic jacks and pipe wrenchs, still no movement. Hooked the pump back up and now no water, we primed the pump about 10 times. Any ideas? Suggestions?
