Naturally, it helps if you already have an online audience you can tap for listening to your regular podcast (like I did), but that hasn't stopped thousands of people from building successful side business ideas into lucrative podcasts—including Alex Blumberg, founder of Gimlet Media who teaches how to use storytelling and launch a podcast. You can also check out this class from podcaster and entrepreneur, Lewis Howes, about how to make money podcasting as a side business idea, which regularly broadcasts for free on CreativeLive.
If so, you might want to consider running your own online thrift shop. Whether you focus on fashion especially, another category of product, or prefer to amass collections of interesting items from all over the internet (but especially eBay!), there’s always a strong demand for items with a story. Give your store a compelling, memorable identity, and it will be seen as much more than a simple consignment store.
