    I have recently started trapping some introduced predators around my local area and have had baits and pre-feed disappear with nothing to show for it, so I decided to get sparky and see if I could catch the culprit in the act.

    All About Catering Web Site

    csshtml

    I approached All About Catering about designing a web site for them when they first started in 2004. They had just opened their shop in Wadestown.

    After discussing what they wanted from a web site with them - some static pages that contained their menu and contact details - and a cost for the different possibilities, and with their logo and current menu in hand, I set about creating a design for the web site using a graphical la. I initially created a couple of different designs and showed them to them. After a little bit of tweaking, they were happy with one of the designs and I converted the design from image to HTML template and CSS. Once the web site was populated and the accepted by the clients, a domain name was registered and a web host was set up and the web site uploaded.
