Great list! I have another to consider that I personally have 35+ years experience providing. Clean up litter outside commercial properties on foot using inexpensive hand tools. It’s almost as easy to do as going for a walk! I started doing this as a side gig in 1981 and soon grew it into a profitable full-time business. I share my experience in my book, Cleanlots.
Etsy: While Etsy's popularity has declined recently, it's still a great resource for selling handmade items online. No need for complex ecommerce sites or merchant accounts or any sort of automation. The company takes a commission of every sale and charges a small listing fee per item. But many still use Etsy as their primary source of income. The best part is that you can also sell digital products on here such as poster designs.
Pinecone is one of the best survey panels out there for earning fast cash, and they pay quickly — usually by the next day — for the surveys you complete. The surveys don't come every week, but it's a nice little bonus when they do because of how fast they pay. Right now Pinecone is open, but there is no guarantee you'll get in just depending on what demographic they need right now.
Number one on the list is also the easiest survey site to sign up for. Once you're in you can take surveys and get paid at Survey Junkie. It's possible to make $100-300/week completing surveys on Survey Junkie! All you need to do is instantly qualify, then view exclusive offers in exchange for your opinions and get access to paid surveys, clinical trial opportunities, and other work offers. Survey Junkie’s interface is super smooth and intuitive (unlike the majority of survey company websites that look like they were built in 1997), and members are paid in cash via Paypal. Oh, and Survey Junkie also has an 8.9/10 rating on TrustPilot — the highest of any online survey company. This is one is the more reputable survey companies out there and I use it often.
