I'm doing a small wall about a foot high a foot wide and 115 long, with a few slight curves and two 90-degree turns. I am figuring 100 hours with two men, including prep and clean-up. Does this number sound accurate? Also, the wall will be flat stone, each piece being about 2" in thickness and 6-12" wide, and there will be about 8 tons of stone to handle. The stone will be mortared in the back (there is only one side facing out) and finished with mortar on the top. Thanks for your help with this one!
