Thanks for all the input guys.
Iím thinking Iím probably not going to be advertising directly for weed control but as a package add on for fertilization clients and full lawn application clients. Essentially bundling it with fertilizer costs for the most part. For the weed dense lawns and new clients I will consider subbing out broadcast spraying...
The motorized electric push spreader just might be a good option.
Honestly Iím more concerned about the logistics of even having proper weather to spray period due to wind and rain. A seasoned application veteran near retirement age flat out admitted to me that if they followed strict rules for spraying by law. They would hardly spray here.
