Freelancer – refer people to developers, designers, and other freelancers you’ve worked with and make 100% of Freelancer’s project commission for the first 90 days. I get a lot of people requesting WordPress speed optimization services… so I refer them to my developers with a freelancer affiliate link and make $125/month in passive income. You can’t use affiliate links to link to specific freelancer profiles, so I direct people to the homepage via affiliate link and give people my developer’s usernames.
Next, you need to set up and build your YouTube channel. Your YouTube channel is your homebase for all your content. If you already have a Google account for Gmail or Google Drive, then you can use that to log-in to YouTube and start setting up your channel. Pick a username that works for you and is memorable (if you’re using an existing Google account you’ll have to edit your username in Google+).
I’m a former lawyer turned entrepreneur with Rodan+Fields (makers of ProActiv, the acne system). After welcoming my twin girls, I decided traveling, long hours, and dial-ins were no longer for me. I wanted to work from home on a part-time basis and Rodan+Fields has allowed me to do that. If you’re interested in earning a solid part-time income on your own terms, I’d love to talk to you!
But don't make the mistake of thinking this will be a passive source of income—you're on call whenever you have a guest and you'll always need to keep the place clean for incoming visitors. On top of just renting on Airbnb, consider offering your guests paid add-ons, like Lauren Gheysens', Royal Day Out in London, England—where she gives visitors a local's only tour of the city, complete with bespoke 18th century costumes.
Create a killer course experience: With your course validated and in the works, you need to figure out how people will take it. Most course creators choose to host their courses (after going down the path of learning how to make a website) on their own blogs. This way, they get all the value of bringing customers back to their site on a regular basis. I host my own courses from a subdomain on my own site so I can easily add more. The course experience is incredibly important as well. And after trying most of the solutions, I highly recommend Teachable—an online platform designed specifically for courses.
If you're serious about making money online, start a blog. Blogging is one of the easiest and most sustainable income sources. As long as the blog is setup the right way, in the right niche, with the right content targeted at the right audience, and the offer is complementary to the content, you could make a tremendous amount of passive income from a blog.
