Wordpress Learning Management System

My client at [login to view URL] would like to set up a LMS (Learning Management System) on his WordPress site similar to what hpacademy has here: [login to view URL] A catalog of the courses, the ability to purchase them as a registered user, and the ability to do drip content so they cannot move on until they pass/watch the previous course/lesson. Additionally, having the ability to put a quiz in the courses as well. The ability to integrate with Stripe so students can pay for the individual content and/or course is also required. Is this something you can do? If so, how much? And can you describe what architecture/plugins you will use?
