Your Idea. It’s not enough to say that you’re going to offer an exercise classes. The people considering your classes will want to know exactly what they are going to get for their money, and it will be up to you to explain it concisely and effectively. Understand that you’re basically giving a sales pitch to potential attendees. You’ll have to really narrow down your topic.
And these days, it has become much easier to make money by renting out a spare room in your house -- or even renting out your car. If you want to rent a room, AirBnB is probably the first place you'll want to start. And Getaround is a great site for renting your car, although it's only available in certain cities right now. Of course, there is always some risk with letting a stranger stay in your house (or use your car) but if you are looking to build your income from home, this is one of the quickest ways.
There are also shopping apps like ibotta, MobiSave, and checkout 21 that give you money back for shopping. And the Walmart app has a savings catcher feature where you take a picture of the barcode or upc at the bottom of your receipt and they search all surrounding store and if a lower price is found they give you the difference back. I have made about 50 bucks total from this app and 20-30 from things like ibotta.
Some companies like 1-800flowers.com outsource customer-service operations to third-party companies who then hire home-based workers or "agents" to take calls and orders. When you call 1-800-flowers, you may be speaking with Rebecca Dooley, a retired police officer and employee of Alpine Access, a major call-center service. When you dialed the number to 1-800-flowers, your call was automatically routed to Rebecca's spare bedroom in Colorado.
When it comes to at-home income, selling your unwanted stuff is the definition of “low-hanging fruit.” Even if you’re resolutely intentional in your purchasing habits, you surely have possessions that you can do without: old kids’ clothing and toys, disused sporting goods, out-of-fashion wardrobe accessories, electronics, entertainment, valuable but non-sentimental keepsakes such as watches and jewelry, broken-in furniture, dusty tools and outdoor equipment, and perhaps even big-ticket items like a motorcycle or second car.
Note: There are dozens of other survey sites out there. These just happen to be the more well-known ones that have a reputation for paying out in a timely manner and not having impossible standards for cashing out. As always, be careful with your personal information. I recommend using an entirely separate email address for survey sites so they don’t clutter your inbox.
