I think you’re at a big disadvantage and will probably loose if the customer is taking multiple bids. Someone that owns a dump truck and skid steer would be done in an hour or so plus another couple hours for hauling. Way cheaper than the 10 hours and 1000 in rental expenses you have. I just priced digging a hole with my 310 at $1500. Now if the customer is smart and goes to talk to the guy with a 325 Cat sitting across the road he would probably do it cheaper since it would take 1/4 the time.
