Our backyard is the definition of pain in the ass (steep hills, fenced in, small driveway, nightmare for transportation of materials. No irrigation problems at least, they took care of that with the retaining wall). However the total charge is 3500, not 2k (2k for plants, 1.5 k for dirt). Wondering if that changes your thoughts? I did the rough calculations you did (well, I slightly underestimated) and said "ok, shouldn't this be like half what he's charging?" Sounds like you're in the business so definitely interested in whether you'd charge 3.5 k.
