I need a CSS/JS developer with PHP knowledge to enhance the look and feel of a small website. It is a dynamic website with 4 similar pages [like view, post, list, register]. Only list is different since we have infinite scroll implemented in it. We have a logo and want to try and theme the site around it. We have some bugs/enhancements required as well like having a modal form when user is not signed in, displaying/hiding some details, etc. The current code uses twitter bootstrap. Please reply with your availability, whether a mockup is possible and a timeframe. Will provide site details via PM only for specific replies. No portfolios please. No upfront payment will be provided. Please do not contact if you require upfront payment.
