I have just been given the opportunity to meet with a current customer about a local shopping center. Their is a major grocery store in the shopping center and very little grass to cut. Most of the property is parking lot, pine straw landscaped islands, and very little grass. What is the best way of estimating a job such as this. I can estimate amount of time needed to complete a single service visit and pinestraw, but would like any ideas you may have. Thanks.
