Custom WordPress website design

Looking for someone to come up with the visuals for a corporate website site in the technology sector that will be programmed on the WordPress platform. Designer will need to work closely with our WordPress developer/programmer. Site needs to have a slick look-and-feel along the lines of the sites/themes listed below (we have noted below the elements of each site that we like). Selected designer must provide portfolio of work that includes some websites that have a similar design aesthetic to the sites below. Preferably will have designed some sites for WordPress. 1. [login to view URL] - we love the friendliness and simplicity of the site, and we both thought it had an awesome, bold design 2. [login to view URL] - navigation bar was great, very simplistic and engaging 3. [login to view URL] - love the white background, it was crisp and clean, the pop of red was captivating 4. [login to view URL] - we hate their banner though! 5. [login to view URL] - very simple (maybe a little too simple, dumbs down the company), but bold 6. [login to view URL] - loved the round navigation bar, bold design 7. [login to view URL] - engaging, hi-tech feel to it, easy navigation 8. [login to view URL] - really great call to action buttons Total number of page templates that we will require visuals for is between 6 and 8. We will also need buttons and in-house promotional banners designed in keeping with the overall site look-and-feel.
