I can give you the info for the mason I use. He is a sub and not an employee. If you look at the pictures on my website almost everything is his work. He can do really amazing saw cut pattern patios. There are way too many crappy masons helpers out there trying to be masons. He did a $60K wall that spanned two homes back yards in Barton Creek West. I think the back fill trucked in must have been 300 yards.
