In this demonstration we use a Rockettheme (.com) template. When searching online for a template make sure you choose one that is compatable with the version of Joomla which you are using (e.g. Joomla version 2.5). Most online templates are free but we would advise you to consider a commercial quality one, such as Rockettheme, Joomlashack etc
You can save yourself a lot of time and frustration down the track, for a modest investment now in a good quality template. Contact AISweb for substantial discounts on commercial templates.
