I am trying to bid on an apartment complex that requires 50 yards of mulch in beds , around buildings etc..The apartment complex is about 6 acres total. Pine bark mulch is $26.00 a yard in my area. My question is how long should it take to lay(2 men), and what would be the most efficient way to do it? $40 per man per hour. I figured Mulch cost $1400.00 delivered. What would a fair labor cost be?
