Responsive Theme Web Design Variants

We are urgently looking for a freelance graphic designer with experience of working up website design visuals. The project we need help with is a Wordpress website, pre-selected responsive theme, customised out of the box with dummy client content and colour scheme. Right now its functional but quite ugly and more like a working wireframe. You would be required to take the existing website layout (sorry no PSD), understand what can and cannot be done to improve it within the context of responsive grid formats and the theme itself, then provide some improved flat visuals using different colour schemes. The website theme is sports & gambling related, for a well known UK association (so not some tin pot website for one man band, it'll look good in your portfolio). You do not need to be a coder or know Wordpress, as a minimum you need to be a first rate graphic designer. Please get in touch with examples of previous digital design projects that you have completed and your expected hourly and/or day rate. All being well this could lead to additional work with us in future.
