Build a Website

Hi, At the moment I have put together a basic website as a proof of concept ([login to view URL]). The aesthetics and layout need to be significantly improved. Apart from the looks, I also need to add an advanced search page which allows users to select filters etc. A total of 4 pages need to implemented; home page (basic search), advanced search page, about page and results page. I have an API that returns the required content as JSON. This website simply needs to make calls to this API and use the data returned to create graphs, word clouds, and a results table.
