Janitorial Business or Cleaning Service business is a pretty good thing to do. You are busy during the whole year, not just during the season. I think that commercial cleaning business is easier to start and to manage than lawn care business and you don't need that much equipment from the beginning. You can try to get some small accounts for the beginning like beauty salons or small offices and see if you like it. If that's something you want to continue to do you can look for bigger accounts then. Good luck.
