well like I've said on here before....I have both a backhoe and a dozer and I can tell you that moving dirt takes longer than you think. It's NOT just a matter of just scooping it up and driving it 250' and dumping. It's a matter of loosening the soil with a hoe and THEN scooping it up and moving it. unless of course it's just loose sandy type stuff, but even then you will want to use the hoe to loosen it up. and once you move it to where you want, you STILL have to wheel pack it down. even after wheel packing it, the dirt will settle even move.
and this doesn't take into account what I call 'the rock clause'. what I mean by that is you can't really tell if there is rock in there until you actually dig it. I'm in the rocky mountains, so I'm used to having to deal with rock.
I think the bottom line is that your NOT gonna move 1000 yards of dirt in a weekend with one or even three machines. no way, no how.
have a local contractor give you a bid. he will have good experience and I bet you will learn a lot.
