I will be placing my first bid on a commercial property and I'm a little unsure of the mulch quote. There are approximately 300 tree rings to mulch. Average diameter is 3 feet. Mulch needs to be 2 inches deep. About 100 are a sound/privacy barrier for the main road. They are staggered down a (fairly level) 725' stretch. Another 100 are staggered down a 1000' stretch but they are on a 5-6' high burm The final 100 are around the perimeter of an open play area. According to my calculations I need 13 yards of mulch for the tree rings that I will round up to 15 yards. I also have a few other beds that may take another 5 yards. So I will need 20 yards total. My price would be $18 per yard. How long do you think this would take 2 guys? How would you tackle it? How much would you quote? I'm thinking along the lines of $2000. Thanks in advance for your thoughts.
