Start by selling your own extra stuff. Then, once you get a feel for selling your extra stuff, go door-to-door in nicer neighborhoods in your town. Develop an eye for what will sell and what won’t (old laptops, for instance, could be a gold mine–if you know how to format them to get rid of the previous owner’s personal data.) Sign a contract where you take 25-30% (or more) of the gross sale. Your customers will be happy to get cash for their old junk, and you’ll make some good money selling other people’s stuff. eBay
Well, what you do depends partly on what you have the skills to do. Obviously you can run a computer, but online jobs aren’t the only ones out there. You could also clean houses, paint, wash cars, babysit, walk dogs, or any other things someone needs help with and is willing to pay you to do. The thing to do is, keep an open mind and don’t hesitate to ask others if they need help. Then, use your money wisely. Don’t just spend it all. Save and invest some too.
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.
If you’re not sure you want to go all-in with an online store, try making some seasonal crafts during the holidays that are easy and require minimal investment. For example, you can gather mistletoe and/or pinecones, tie them into bunches with ribbons and cheap bells, and sell them as decorations. If it goes well and you enjoy the process, think about opening a more permanent storefront.
Enjoy making silly videos? Even short, silly videos can sell products online. Find an product worth promoting that has an affiliate program, then target your video toward potential customers of that product. In your video summary on YouTube, place your affiliate link for the product, and after the video, do a 30-second still frame showing a short URL where people can buy the product. If your video is funny, informative, or useful, you may sell some products. Big tip: Try to promote a product that makes you a fair amount of money for each sale, but doesn’t cost a whole lot for the potential customer. You can find products on Commission Junction, for one.
High-ticket consulting or coaching: You could sell your own high-ticket consulting or coaching products from your website. You'll still need a website, merchant account, sales funnel, lead magnet and many other items. But you can easily earn a substantial amount of money from each individual customer, making it well worth the arduous setup required.
Creating a jobs board website can be another profitable venture. The ‘jobs’ field can be quite saturated, so it is important to find a niche that is still crying out for a jobs board website. Monetize this type of site by charging businesses to list their jobs on your site. Those searching for jobs could also be charged a fee to access the higher paying job adverts.
