Rate seems pretty high to me.

State average for corn $0.131/bu up to 15 miles, then $0.014/bu/mile over basic mileage.

On a 50 mile haul I believe that comes to $0.621/bu (13.1 + [35*1.4)]; compared to the Iowa link which pays $0.252 (low .36 - hi .40) for 100 mile haul, if I'm reading it correctly.

$558.9 for a 900 bu load - didn't some of you recently think $70 - $85/hour was high?  $5.589/runnning mile would work nice in my budget!  OR what are your fuel prices??
