If I am being honest, the website could be improved quite dramatically. The first thing I would achieve is to make all the content centred. Then the next thing I would do is to change the font to something other than Times New Roman. Colours are nice though and contrast well to a certain degree. Another thing I have noticed is the menu is not the same on all pages, and neither the style doesn't match throughout, for example the main index page compared to the repair rates page.
With a website like this, it is all about first impressions, especially when you are trying to sell a web design service as well. People tend to go from what they can see and how they judge the work they see is whether on not they choose your company.
Hope this helps, message me if you want any more information or help
