i'm relatively new in this business. i've got about 6 yards right now and i'm looking to expand, but i'd like to throw this question out there first. is it customary to charge additional fees for other services? (ie. topping shrubs, cutting down dead limbs, vine removal and such.) i don't mean felling and hauling off a tree or something like that, just minute things that don't take too much extra time. i mean is that just part of the regular service or should i be entitled to other fees? any advice would be appreciated.
