I have a $$ figure I use per foot of perimeter edge, I do use this figure where are needed and don't use it when they are not needed (such as a straight walkway that uses all full pavers with very little needed cuts). I then have a figure added in for curved borders in which all the pavers for the soldier course need to be cut. All of this is figured in to my job cost which is used to build my proposal.
Why do people not respect us as they do other tradesmen? Because every Tom, Dick, and Harry doesn't think he can be a plumber or electrician!
