Given the caveats you've presented, and that it seems to be a straight install of a canned template, it's difficult to say much. It looks good. The responsive aspect works. I'm not a fan of the huge "call to action" being the first thing that hits me, and in doing so, it takes up 100% of my screen. Your logo is the only thing that indicates what your company might do, so a huge "call to action" is putting the cart before the ol' horse.

I know lawn & landscape marketing, branding, and web strategy. I'm not anonymous, I just don't self-promote.
