Go to a local hardware or sometimes a Home Depot in the area where you want to do the well, usualy a rural store carries these things. You will want to get what is called a "Point". This is driven down by hand but you will not be able to pump water if the water level is more than about 30 feet because of what is called dynamic suction lift. The water will start to separate at the depth of about 30-35 feet. There is a device that is put over the pipe that is threaded into the point. This device will allow you to kinda hammer the point down. If you don't hit water you will most likely need a backhoe to pull the point and piping up. Total cost with a hand pump should be in the neighborhood of $150.00 - $200.00 for the point, pipeing and rental of the hammer device.
