I already posted a question about removing lava rock and got some prices of around $400-$500. The customer wants hardwood mulch placed where the rock was. The total area is approx. 330 square feet and various mulch calculators come up with around 3.1 yards. Should I get 3.5 yards to be safe? There are about 6-8 small shrubs planted in the area. I am bringing the rocks up to the cabin so I don't have any disposal fees and I'm using my pick-up to haul the new mulch. The area is right next to the driveway and the maximum distance to wheelbarrow the mulch is about 30'. A yard of mulch is $22. How long does it take one person to move a yard of mulch? I know there are many factors that determine this but any advice would be appreciated. How much do you raise the price of the mulch, 20%, 40%, more...less? I have seen mulch prices of $40-$85/yard but if it takes me an hour to move the mulch ($50/hour) and mulch is $22/yard and I charge $75/yard I make nothing on the mulch. But if I charge $80/yard (about $30 for mulch and $50 for labor) I seem to be on the high side. So would you remove 330 sq ft of lava rock and replace it with mulch for $800? Customer doesn't want landscape fabric or edging. Thank you, I appreciate any advice, Joel B.
