I really like your apply for an estimate page. I may borrow that idea and ad that to my own site.
I would recommend a Home page or landing page, that tells the visitor what your business does and the benefits of using your service over others. List your experience in lawn care, affiliations, Ect. Then ad an about page where you tell your story, history, why you like doing your job. I can tell you put lots of time into your wordpress blog site. I tried wordpress and found it was taking too much time to learn. That's just me, not a big computer guy. So I went with a web building website and found it much easier. Best of luck.
