At the risk of repeating what others have said, what an amazing/wonderful/fantastic list. Thank you so much – this will keep me busy investigating options for a while ! I have had some small success with Audio Jungle (part of the Envato group of sites) – uploading short music files that I have created once, yet they keep on selling. I like your Fiverr example too http://www.sidehustlenation.com/self-publishing-platform-outsold-amazon/ – I’ll have to try that one !
People are always searching for one-of-a-kind venues for meetings, parties and weddings. Why not earn some extra money off the space you already have by renting it out for events as a side business idea? If you own a unique venue, like a studio, warehouse or boat, UK-based company Tagvenue will connect you with clients looking for somewhere special to host their event. Not a bad low-effort side business idea.
This next category is one of my favorites. And, it applies to almost everyone looking for a good side hustle. Why? Because it is something everyone should be doing regardless of whether they are looking for a little something to earn a few pennies during commercial breaks that requires minimal effort or they are looking to create a full-time income from home.

You can use desktop publishing software to create newsletters, magazines, books or even marketing materials. You can create the content for your desktop publications, or you can pay a writer to create the content for you. Alternatively, you can advertise your desktop publishing services to design and create newsletters and books for others with their content.
Once you have a little bit of money, you need to start investing it. The goal, of course, is to turn your investments into a passive income stream that will pay you for the rest of your life. It doesn't take much to get started. You can get started investing with as little as $1 with these free investing apps. Then, add another $100 each month and you'll grow your nest egg into something powerful.
