I have read your requirements. I am an expert in creating responsive custom and Wordpress themes and complete websites from PSDs. You can go through my previous work history regarding responsive Web Development. I have 3 years experience in WordPress, HTML5, CSS3, JS, JQuery, Ajax, TwitterBootstrap, and PHP. I have worked on 300+ projects. I have worked in WordPress, Joomla, Opencart and a number of CMS frameworks and custom websites as well. I would love to work for you for long-term and I can provide my old projects if you say.
