325' is pretty deep. If it is hanging on PVC or Poly pipe, and it is not stuck, you and a couple of friends can probably pull it out. If it is steel pipe, it's gonna be REAL heavy. If you can lift it, anyone can pull and set a pump. However, it is the little stuff that makes a pump man worth while. Knowing how to get a pump unstuck, how to splice the wires, how to attach the wire to the drop pipe, knowing that you can't attach a steel fitting to a brass or stainless one without insulation, and simply knowing something isn't right when he sees it, makes a pump man worth his salt.
If all goes well you can save yourself a little money. If you drop that pump in the well, $2,000 for a pump man would have been cheap. Even charging $2,000, you won't see very many rich pump guys. We learn this stuff the hard way by having to spend 3 or 4,000 bucks to fix your $2,000 job when something doesn't go right. Some pump guys have some old rigs that are paid for but, most have to make payments on rigs that cost from $50,000 to $250,000. Then there is the insurance payments, fuel, tools, license fees, phone bills, advertisements. Then if your employees show up, you have to pay them as well. Something goes wrong under warranty, and there is another trip without compensation.
It usually gives people a good appreciation for a pump man when they pull a 325' well themselves. Everybody should try it once, then the price quoted by a pump man doesn't seem nearly as high.
