At the time of building this site my client were the only company in Cape Town selling PVC Double Glazed windows. The website was a marketing tool for them, so the site was coded in xhtml/css and had plenty of keywords for Double Glazing. After a month of being online the site was the top result in Google South Africa for Double Glazing.
A few years later I asked the client how the website was doing at getting them new business and they told me the website was how they were getting most of their business.
Below are some screenshots of the project.
