Hello, I am looking for a skeleton or theme with the following features, thanks

Hello, I am looking for a skeleton or theme, easy to configure that has:
1 Menu Pages
1.1 Two levels deep of Subpages (Sub Menus)
2 A blog, as one of the Menu or Sub Menu item, with pagination
3 Is there a Course plugin? I have not found any on the downloads.
4 Is there a stand-alone online chat plugin? Because the ones that I have found on downloads are connectors to live chat services, am I wrong?.
5 It would be ideal if the theme has some documentation
Thanks and regards
