A basic Google My Business template website is free and has some higher ranking ability because you are using their platform. Nothing fancy, edit the template. Get it verified and publish it. Make a post every day or so, post pics. Share your page. Get your customers to do a google review on your page. You don't have to build some fancy website or spend money just to get a web presence. If all you are doing is mow and blow, then it is even less to put on the website.
