I need to remove 450 sq. ft. of vine cover from existing beds. The customer wants to take it completely out for a new look and he is tired of the maintainence. I heard you have to keep cutting it back and applying round-up for several treatments. How would I charge on something like this. My labor rate is 35 per hr. I have no idea how long this is going to take. Does any one have any insight on this situation.
