Do you know how many cubic feet of dirt you have to move? Seems like a lot.

How do you get the dirt out to the top when you get really deep. You have to have some kind of bucket/lift system to get the dirt up.

I doug about 5 1/2 feet, and it was getting hard to get the dirt out. Word of advice, don't pile the dirt around the hole. You have to move it. Cause when you get deeper, you're not going to have any place to put all the dirt if its piled around the entrance. You're going to have one guy moving the dirt that is on the surface to another spot off in the distance.
