You may have some design/coding limitations becuase you`re using homestead, but watch the size of your image files. For example, the image file on the contact us page is 125K+. Try to keep image files lower than 40K.
Also, make sure you have a different title and description for each web page
If you are not going to employ a "normal" menu for navigation, you should include a link to all your pages on the bottom... especially the list of your services.
Design wise... the big button-like links are not a favorite of mine . Text links would be fine. Also, I suggest you add a mouseover effect for all your links (you do it at the bottom of the page).
