Upwork: This website offers a great marketplace for selling just about any professional service. You don't need a merchant account, website of your own or anything else for that matter. All you need to do is be able to provide a high-quality service at a reasonable price. But be informed, you will have to compete with many others that are constantly bidding on open jobs.
You could also opt to use existing websites for making money. These include both active income and passive income methods. For example, you could sell some used items or invest in creating some digital designs that then can be sold on merchandise. Again, devote a sizable portion of your time to passive income so that you can slowly build up earnings that will arrive on autopilot without any extra added effort.
I should warn everybody about SlicethePie. I have been a member of slicethepie for about three or four months, and while everything was going great, they are quick to lock your account for any type of reason, even when you are not breaking the terms and conditions. I made sure each and every time I used that website that I was not breaking their terms and conditions, and my account still got locked. So I would just watch out for that. That is just my personal experience with the website though. It may be different for other people.
Fiverr is one of the biggest providers in the gig economy on the web and you can sell a wide variety of services and products through this medium. Do the research and find out what you can offer. However, keep in mind that like any other money-making task, it takes time to succeed here. And stellar reviews will help you generate more and more income over time.
The biggest advice I can give is to pick a small niche, set up a site and start experimenting. Make mistakes and learn from them. That’s the only way you are going to succeed. Of course, have realistic expectations. It took me more than 1-2 years to start making decent money. But the beauty of it is that once you make that first dollar, you know it works and at that point it just becomes a matter of scaling it up, working harder and smarter to scale up your business.
Be professional. When you submit a résumé, don’t type it in ALL CAPS and please don’t avoid the caps lock like the plague. Know how to use it without looking incompetent. Write in complete sentences with proper grammar. Of course, there will be exceptions, but even with the exceptions, you must keep it professional. You’re building their view of you.
