Welcome to the site and good luck with your new business. It's kind of fun...at first! If you've never operated a zer-turn mower before you can expect to do some turf damage while turning. I've been mowing commercially since 2002 and still do from time to time. It's a good idea to carry a small bag of grass seed. Also these mowers get stuck pretty easily. I suggest you have a plan for when it happens. That's my free advice. Anything more gets billed at my consultant rate
