Website Design and CSS

Hi, I need a very creative person to help update my website design and layout. You must be able to review the mock design I provide and implement it on the site and suggest improvements. The ideal person will have a rating above 9. The website is developed in Php and you will be working with our php developer to complete the site design. I have a sample design I created that I would like to implement. I believe the work will mostly be CSS with some minor graphics. Please include sample of your previous work this is very important in choosing the right candidate. A NDNC will need to be signed to work on the site. I will send more details to those that apply. If you can provide an expert guarantee it's welcomed. If you don't have very good CSS Skills please do not apply as it will only delay my project timeline. A bonus will be considered for very Good work and design. Adjusts maybe made to the budget amount depending on your skill level and performance. Thanks.
