Web Design HTML & CSS

I have the web design templates in place and I'm now looking for developer to build the site. This is nothing to complex. Simple HTML and CSS but please feel free to use other languages. I have experience in HTML, CSS and some JavaScript so prefer if you stick with those 3. Please use up to date CSS rather than breaking up the images on the designs. The only section on the webpage that can definitely be done as an image is the key inputs diagram.

This is one page website. You have a home page > User can select the buttons which appear on the left hand side. These are

Key Input & Ouput

Cost estimate

Concept Select Phase
Detailed Planning Phase
Execution Phase
