Specifically related to lawn care, adding to Ben's recommendation, I really like Wendy Komanchek. In addition to using her to work with some of our own clients, she's written for, well, just about everyone. https://www.linkedin.com/in/landscapewriter. We're seeing fresh content and blogging having the biggest single impact on rankings and the demand for it has been a hockey stick over the last year, which is why we brought in Wendy to help cover the increase. For a variety of reasons, I don't typically outsource our own client work, however she's been the one I would readily use and recommend.
