What is it about that hole?

I stopped by Jeff's for a face to face. Interrupting his nap and discovering he was sick with a really nasty cold, I had to swallow my shyness and brave the question to him. Did he want to loan or rent me his backhoe...did he want to do the digging? He said no. So, onward.  Any other ideas? I asked his advice about backhoes in general, size, renting from an equipment place, etc. He said there is a lot to know about digging that foundation hole and is really more than I think. This hole must be really complicated???? He was discouraging about my doing it.

 I also asked about wells and he said definately have it pounded. He said the casing goes everywhere there is not rock. So if the rock is the bottom 50 feet then the casing will only be on the top 20 feet. (you know I'm putting out vibes to hit pure, perfect water with required output at 70 feet). He said the builder or the well guy could dig the trench hole for the water pipe to the house. I didn't know that the pump is small and fits inside the well casing pipe. His is submersed at the bottom of the well. 

We talked about the width of the driveway to get the backhoe and well truck into the woods. Anyone he knew to stay away from? He said no. He told me about his septic leech field and the path it all follows, tank and pipes.  Also to have drainage pipes around the house foundation and have them drain off at two corners.
