Thanks for sharing! I also recommend social media. It’s not for everyone, but you can make fairly decent money with it. I have 100,000 followers across my social media platforms and I regularly get asked for partnerships for sponsoring. Plus, it’s a good way to promote and a very easy way to leverage an existing audience for pretty much everything.
Fiverr is a popular platform for offering services. You can create your own Gigs to have available for sale. As the name suggests, Gigs are available to purchase starting at $5 though you can offer upsells to increase your earnings. You do need to wait 14 days between completing a Gig to being able to withdraw your earnings by PayPal. There are fees associated with these transactions.
