Let me preface this by saying that I have very little experience in moving mass quantities of earth. That being said, I have a plan for a cheese/wine/beer cellar cut into my sloped backyard and wanted to pick some brains on the feasibility and cost of getting it done.
A backhoe will cost 680/week from Hertz, and I'd like to have the dirt moved relatively quickly.

A quick 3d SketchUp of what I want:
Anyone have any good experience and/or recommendations that could make this as easy and inexpensive as possible?
