Marketing my Articulate Course

Hello,

I am a former teacher with a Master's degree in Home Economics Education. I am new to e-learning. I would like to develop a health-oriented e-learning course in Articulate for adults. I am self-employed. 

I have three questions:

1. Once my course is developed, how do I market it?
2. Is an LMS application needed to "house" this course or will a landing page suffice?
3. Where do I place the landing page?

I don't want to go through the effort of course development if I cannot sell it.

Thank you.
