1- Create a Drupal page and set it as home page
2- Re-create the 2 HTML pages on Drupal (layout+style+content as nodes)
3- Set some blocks to be shown by default on all website pages
I already installed Drupal 7.27, Jquery update, views, panels, display suite, drupal bootstrap and all it related modules... So if you have experience with converting bootstrap websites to Drupal, you are welcome!
