I have a customer that has 29100 sq. ft of grass area they want aerated and overseeded. The area is open with no obsticles but the back and sides (26000 sq ft of it) is a pretty good slope. I would assume a pull behind would be the best tool with keeping expenses in mind but what would you guys charge for a large property. Use the same calculations regaurdless of Sq. ft or does the rate go down some as the Sq. Ft. increases? Thanks!
