CSS design and small PHP job on Joomla site

We have a small website with Joomla and Virtuemart installed. We bought a template for Joomla and the job is mainly consisting of 2 parts: 1) To change the CSS layout and design so that the design of the part concerning virtuemart blends into the the existing new template design. This should be done with CSS only and we need someone with a feel for things that look good and harmonic. You should have a feeling for colors and know how to make tables and input forms look appealing. 2) Fix a bug in the virtuemart code. When the SEF function of Joomla is turned on, a 404 error will be generated when the sopper clicks on "checkout" as the url is not properly translated. In order to fix that issue, one needs to go into the code that is handling each step of the checkout process. All in all this is no rocket science, but we are looking to build up a team to do business with in the future again as we will be using quite a bit of Joomla. The detailed job description is in the attachment. It contains pictures and detailed descriptions. If you need clarification, please contact us through the message board.
