I tell customers straight out that if they are looking for the lowest price they should call somewhere else. I don't play around with "the other guy will do it for $xx.xx" I don't care what they will do it for, this is my price and that is what it will cost for me to do the work. There may be some disagreement, but I've used similar lines to yours when dealing with customers. I don't care if anyone disagrees with me here, but it puts things into perspective for the customer. If you are like me and work hard to educate yourself continuously then you will agree that there is more to taking care of a lawn then "just cutting the grass". Recognizing issues before they become problems, and being able to properly cure and prevent future issues is not something that "the kid down the street" can do. It takes education and experience. I do the same with irrigation customers. If they say something about someone with a lower price, I ask them if they would hire the a plumber based on price. The answer is usually no, I then explain that the difference between the plumbing in the irrigation and the plumbing in the house is: 1.There are more moving parts 2.There is more pipe in the yard than in the home 3.There are electrical components in the irrigation. Then I ask if they know what a plumbers rates are. Most no longer have a problem with the price after that.
