This job is in 2 parts.
1) To create a mobile friendly version of an existing custom Wordpress theme using css media queries. The Wordpress theme currently uses a fixed layout but we'd need the theme changed so that the site is more convenient for mobile phone visitors.
2) The existing Wordpress site is using WordPress 3.3.1. Updating it to 3.5.1 results in some "featured images" in certain posts not being displayed. The theme should be updated to use code compatible with 3.5.1 so that nothing is "breaks" when Wordpress or plugins are upgraded.
If you have any questions, please don't hesitate to ask.
