Developing website, Sizeguide.net

I need help to develop the site [login to view URL], both design and contentwise. It is built in Joomla, and needs a new template (use a free template, or create one yourself), better conversion charts, new images, a new font, and a complete touch-up of everything. No SEO or copy writing necessary, just help with developing neat and (very important!) correct charts, for conversion between different size systems. These charts has to be double- and tripled-checked for accuracy and reliance, and should suit the template and site design. If you have any other ideas or tools for easy conversion between size systems, please suggest this instead. The site design should be based around the current header; that is light, easy and cool, preferrably white or light grey. The illustrations and pictures should be positive and neat, and useful. Images/illustrations should be free of copyright. The basic structure, with three columns, should remain, and the current header should be used (size of header could be changed.) If you also would like to provide unique, suitable content to the site, please note this in your bid, with a separate cost for this. Any suggestions of improvements while developing the sight are very welcome, and great ideas will be rewarded. All the work should be done within Joomla, and you will receive the login and password for the site, during your work.
