I have a mowing/snowplowing customer who wants me to install 54' of the 6' high vinyl fencing, 48' straight, 6' at a 90degree. I will have my cousin who is a carpenter help me with the install. I would like to know how long will it take 2 guys to install this? I told them they were looking at about $500 - $600 for the install alone. The material cost is about $900. Am I in the ballpark? Any comments from guys that have installed this would be appreciated.
