I have a paver patio and retaining wall job to do an estimate for. It is one raised patio (using Versa-lok to raise it) 88 square feet, half circle patio with a 14 foot radius ( about 310 square feet I think) and a walk way that is about 33 square feet. The versa-lok section is about 20 feet long and seven inches high (includes cap with half block buried. I have my materials figured at about $3900, rentals (New Holland, trucking, and compactor) at about $700. I total estimate is about $8000. Does that sound like a reasonable estimate? any help or suggestions would be appreciated. It is all being done by two guys.
