You have a good start with your site. If you would like, I would like to leave you with some comments that are important to getting your site ranking well in search engines.
Your homepage title is still the default 'index' You can find this in your code between the ********* </title> tags. These tags are very important towards explaining to search engines what your page is about. So something that explains who you are like perhaps 'ProLawn Lawncare and Landscaping - Columbus Kansas' is I think a better choice.
Looking at your page titles on the other pages, they say the same things and have very simple one word descriptions. So again, redefine those titles to better describe the page and say what the page is about and how you are.
There's a broken link too in the footer menu.
I hope this helps! all the best,
