Around 30 pages are there but it's ok if you just convert just 2 pages completely as it's one design in all pages. 7-8 graphics buttons should replace to css buttons. There may need some graphics adjustment for drupal, The design must be 100% same as now. All pages needs to be in drupal Xhtml. Must follow drupal template guide line. Respond with examples and deadline. Cheapest and the best ones wins.
