Just about all the "good" Dozer guys can shoot laser, generally they're pretty accurate. Back when oil prices were low, i.e. 12 months, a local operator could be had for a minimum of $55-60, per hour...add another $10 per hour if they have to travel. I don't think diesel prices have skyrocketed like other gas prices, but you're getting a good deal at the above rates.
There are some variables shooting waterlines and acreage. It's easy to guess...it's a lot harder once the digging begins...clay depth varies, and there's unknowns with rock/limestone/gravel/etc.
