No matter what kind of purchase we’re making or how much we intend to spend, all of us follow a relatively similar path when it comes to deciding what to buy. This buying process, or stages, was first introduced by John Dewey in 1910, but even now — more than 100 years later — it’s still the foundation of understanding buyer behavior and marketing funnel creation.
As a software engineer myself, I can tell you that building funnels from an application standpoint takes massive amounts of work. There's a great deal of coding and integration that's required here. From email systems to landing page implementations to credit card processing APIs, and everything in between, so many platforms need to "talk," that it takes the bar too high for the average marketer. 
Content also includes developing your final offer, that is to say your course.  Take some time to write down exactly what your offer is.  What is the price for your course? What are the benefits and outcomes for students? What problem does it solve? Why should they buy a course from you? You will need this in the future when you create your email campaign. More on that later.
Much of this is steeped in buyer psychology. The best marketers in the world know that there is a psychological process that must occur for prospects to whip out those credit cards and turn into buyers or even hyper-active buyers. One such person whose perfected this process is Russell Brunson, an "underground entrepreneur" who founded a company called ClickFunnels, a sales funnel SaaS business that empowers marketers from around the world to build marketing automation without all the hassle.
