Hope your mom is doing better. My prayers to you and all your family.
Good start to your business. Hook up with a reputable and revered local family owned nursery. They may be able to get you accounts without having to market the usual way. Also, places like that are a gold mine for technical information and updates on new things. Anybody can mow, but spotting pythium blight( et al) b4 anyone else and knowing what to do makes you indespensable.
