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.
Webinars are quite possibly one of the most potent ways you can make an exorbitant amount of money online. You'll need an audience to train and you'll need to know what you're talking about. Of course, this usually requires having a website and some semblance of an online presence. However, people can still do webinars without all of that. For example, you might have a sizable social media following and you train them every week on something to do with social media. But you will need a product to embed and sell at some point. Don't worry about it in the beginning. In my experience, the best webinar platform out there is GoToWebinar.
My local Craigslist.org is the first place I go to sell something. It’s best for items you think will appeal to everyone (therefore justifying the smaller audience) and large items that can’t be shipped. Craigslist.org is great for taking your yard sale items online for local sales. For example, a friend recently bought two fans from people that live close to him. These one-off type items do very well on Craigslist. Just remember to use common sense and be safe out there.
Take good pictures. Some of the options below don’t require you to actually take the picture and sell the product, but for the ones that do, make sure you take a clear picture that makes your product stand out from the others. If you’re going to be taking a lot of pictures, set up a small “studio-like” area in your home with a backdrop and proper lighting to really make your pictures come across as professional. And of course, you’ll want a good camera too.
@Philip Taylor So by what you’re saying, I can be an unaccredited doctor or surgeon for someone (for example) but do it at a much lower rate than the accredited doctors and surgeons. Since I know what a scalpel is and I wear rubber gloves, I’m a doctor. So, I don’t have to have to respect the profession of medical science at all since I think I know what I’m doing and just go for it.
Refinish old furniture from thrift stores, yard sales, or online ads. Sand down the furniture to smooth out the surfaces and buff off some of the old paint or stain. If you want to restain it, use a lacquer or paint thinner to remove the stain. Then, re-stain the piece. If you plan to repaint it, apply a primer and let it dry. Next, apply at least 2 coats of paint, letting each coat dry for at least 24 hours. If necessary, add new hardware to finish the piece.
