I've been thinking latelt about other ways to expand. It seems the only guys in my area doing chemical applications are chem lawn. They currently treat atleast half of the lawns that I maintain so I started thinking maybe I should add this to my list of services. But is it worth becoming certified, spending $3,000 or more on a spray rig, plus the cost of all the chemicals? If there was such good money in this wouldn't everyone be doing this? For you guys that do this what do you charge for say a 1/4 acre lot? How many visits per year, and all that good stuff? Thanks for any and all help.
