Importing Tutorials $$$

G,day i have just installed drupal with the intentions of installing a module to handle my tutorials on my site. I wish to have a module that works just like good-tutorials.com and would like to install it on my drupal. Can somebody please tell me where i can get one and import my tutorials from my previous site. As i will need to convert my mysql database information into the module so i can easily intergrate my old tutorials onto the new system.
