this year I have pickup 10 new ones along with my current customers. I finally did convince one lady to end her current lawn guy(im the plow Guy) as i was getting tired of them blaming weeds in her yard from the winter plowing. A free spring cleanup and a free mow on her business and house won her over.
Im in the same boat as you by give free weekly edging. People appreciate that and it looks more apleasing to new customers/neighbors.
