Wow, thanks for all the input guys!
Another question: I understand that there are many different services people offer in the lawn care space, some of which include basic mowing/trimming, tree care, core aeration, fertilization, weed treatment, etc. How did you decide which services to offer? Also, I imagine that some services are more easily included as add-on's to basic lawn care, while others require much more extensive training, licensing or equipment. In your experience, which services are the best to get started with, and which ones should I look at adding on down the line?
