Rocket Themes is another good theme developer we feature that creates a number of different themes, not just for WordPress but also Joomla and Drupal. They have a number of themes but not all are responsive so we only feature the best ones. One theme costs $50 for one theme or $300 for all of the themes with their developer package.
