I set a few residential well pumps a year, an additional way to make money with the 30 ton. I set them quicker and cheaper then the guys with the little trucks, often 100' of pipe at a time! Plus I don't have to back up directly over the well, a huge advantage. See what your local pump guys charge per hour, you may find, like I did, they charge as much as I do per hour, while having a fraction of the amount of money tied up in equipment. It's not rocket science, pretty straightforward work, I learned it when hired by one of them to reach over a garage that had been built since the well was drilled. Plus I had earlier set a couple dozen solar powered water pumps, since then I've been involved with about 50 or 60 well pump jobs, always coming in cheaper then the "real" pump setters by quite a bit, while charging my usual rates. I am NOT popular among them, so I keep it somewhat under the table, I let the homeowner make the decision who to use, and usually have him do the wrenching, assuming he is into that, here in my rural area most are handy.
