Does any one use a general percentage for marking up materials sold to a customer? In my case I have roughly 180 ft of curved and winding flower bed to put a boarder on. It is well kept with a definite edge. I recommended the metal landscape edging from lowes which is what I used on my last house and loved the way it looked and held up. Depending on which color this client chooses, it could either be $9 or $13 per 8 ft section. These sections take any where from 2-10 min depending on the soil and the shape of the given area. For this job I'm estimating 2 men for 3 hours. Either $220 or $320 in materials, depending on color. Any suggestions for pricing per foot?
