I am new to hardscaping and have a customer who wants columns around their patio boxed up and have it stack stoned. They are providing all materials as they have family in stone yard business and all I have to price is labor. Would you suggest per hour rate, which seems to my benefit to overcome any problems or delays or per square foot? The columns are 10 and I will square off with cinder blocks and stack stone around. Pretty straight forward but no idea as to how to charge or what to charge. What are guys getting price wise for this work? I am in KY and understand prices vary greatly but I could use your figures to give me a ballpark to start with. Thanks for the help.
