We have created the theme based upon customers PSD designs, each page of which has been created in XHTML format and after that all pages have been transferred on PHP template. Each page contains a lot of images, so the task consisted of speed optimization coding to prevent any problems with content in future. The code is valid according to W3C standards (including crossbrowser testing). All communication was performed through our Project Manager. There were several additional  developers from the client’s side, so the existing team have covered 24 hours per day.
