if your able to make an online e-learning?

If I'm able to make an online e-learning, then I would like to use a password-protected site where only the members can access. Then those lessons would be in pdf style which can be downloaded through a link that I would be providing in my website. I have not made a start up yet because I don't have the time to be online most of the time, including the finances that I would be using. I just hope that my dreams will come true some other time. Good day.
