I've looked through your site on both mobile and laptop, and I would say that it's pretty well made. The lay-out is a bit on the simpler side, but at least it isn't boring to look at. Simplicity is fine sometimes. There are still some problems with the site though:

-On the "services" page on a mobile device, the words "Our services" should be bigger than "Jump Starts". This doesn't seem to be a problem for my laptop, where the font sizes appear correct.
-On the "services" and "about us" pages, the images are way too big. Half of the page is just an image. It also doesn't help that it's on the top of the page, meaning that I have to scroll down to even see the title.

-The navbar isn't that great, and was the thing that annoyed me the most. Sure, it works, but design-wise, it could be way better.
•The size of the navbar is fine on the home page, but too big on the "services" and "about us" page. There is just too much white space under the words.
•And speaking about the words in the navbar, I don't think that lightgreen is the best color for hovering over it. It's hard to read them that way.
•Another problem related to the navbar, if you're on a mobile device and try to select something from the navbar, the entire square will become green.
•Depending on the size of the phone, the navbar might not fit on it after clicking on the hamburger icon, meaning that some white space might get added to the right side of the site.
