Design responsive and mobile ready website

Design a responsive website for Apple / Android / Windows Phone mobile devices as well as desktop browsers. It shall consist of three pages: - the landing page with some sections. A background image (full scale) or a color shall be configurable for each of the sections. One of the sections shall contain two link buttons. - an example for a static page, with different standard elements that can be used for expanding the page by our own (add further static pages) - a product configurator page, where the main part is the configurator window (has to be as large as possible on all devices). For all three pages HTML does already exist and has to be kept in mind. But the static as well as the landing page are really rudimentary. The sources are attached. Currently Foundation is used to structure the user interface, Foundation will be preferred, but also other known frameworks (e.g. bootstrap) could be used but have to be agreed on. We expect a clear, simplistic and classic approach - mostly bright colors shall be used. A central position for logo integration has to be foreseen.
