I have a custome who hass three large flower beds and trees, and wants me to remove and haul off around three to four yards of old red mulch using a rake and a wheel barrel and my equipment trailer. Then he is delivering 10 yards of new mulch to replace the old mulch and also place around all of his trees. The trees are scattered over 2 acres. i will have acces to a tractor with a bucket. I will have one helper and am not sure what to charge. What do you guys suggest???
