Convert HTML website to Drupal

Hi, We have designed the clients website as HTML but they want it converted to Drupal without having any of the user login/registration or search functionality. They basically want it to be a CMS website where only they can login via a URL. They are set on using Drupal though. The design can be seen at [login to view URL] Please note that the button to EOY Studies is to change to display the gallery of photos now. Please advise turnaround and cost.
