I agree with Steve.  Do you know of any local contractors that could do the heavy work for you?  It might sound less than desirable at first but a skilled person on a machine to hog some material out can be money well spent.  A laser-guided box will work best when you are +/- 1-inch of desired grade.  If you are further out than that, it can take hours to get to grade.  Yards of material add up fast if you are a 1/4" out...let alone an inch.  Trust me, I know.
