On average over 20% of all website visitors view sites on a mobile device and that number is only rising. All of my sites are developed with fully mobile responsive designs that adapt for the iPhone, iPad and all other mobile devices.
In today's market, websites need to be accessible on any device, including laptops, tablets and smart phones. 100% of my projects over the past 8 years were built on the Joomla CMS. There are over 7500 Joomla extensions available, that will allow you to put your web site to work for you 24/7. No employee can offer that.
