Next, you’ll need the right tools. You can be as complicated or simple as you want depending on your comfort with audio equipment, but at the minimum you’ll want a microphone and software for recording your voice. Companies like Behringer, Blue, Focusrite, and others sell studio-quality plug-and-play podcast setups that can get you recording today.
Considering that you have a finite amount of time, passive income should make up a large part of your work. If you're serious about generating any semblance of income online, then passive income should be one of your sole goals and ambitions. Why? Wouldn't you prefer to do the work one time and get paid repeatedly as opposed to relying on your time to generate that income? Invest the time at the front-end so that you can reap the benefits on the back-end. This means putting in a bit of sweat equity and not getting paid today. Rather, you'll get paid somewhere down the road. And you'll continue getting paid whether you keep building that passive income stream or you stop.
Mechanical Turk: You’ve probably heard of Amazon’s program. If not, here’s the simple version: You pick tasks to complete—“anything from conducting simple data validation and research to more subjective tasks like survey participation, content moderation, and more,” describes Amazon—and get paid for your efforts. Since you’re going to see a lot of lowball offers on the site, I recommend using the unofficial /r/mturk subreddit to help you hunt for juicier opportunities.
FlexJobs is 100% legit. While it may not be necessary for everyone, if you have limited time available to dig around on the internet and vet companies for legitimacy it’s well worth the investment. They research each job lead to make sure it is truly remote or flexible and it isn’t a scam. I’ve had a membership for a very long time and find it well worth the small investment.
Find a profitable niche. Starting with your interests, write down as many niche ideas as you can. Think about topics people might search online. Ideas include passions (like surfing or body building), fears (like spiders or speaking in front of crowds) and problems (like getting out of debt). Do keyword research to see it others are interested in the topic. Find out if a domain name is available that matches the keyword 100 percent. 
Before getting started with any kind of “we’ll pay you some minimal amount to do stuff” service, read reviews. What are people saying about the payments? The opportunities? How long it takes to get paid? Are there any creative methods a person can use to maximize their profits for the work? Is the work something you can actually see yourself doing, or will you likely quit a few minutes after you’ve finished your first project?
How to Get It: You can apply directly through companies, such as Stella & Dot, a jewelry company that had over $100 million in sales in 2010, who is always in need of stylists. A few others include Avon (household and personal care), The Cocoa Exchange (chocolates and more), and Alice's Table (flowers). You can also visit the Direct Selling Association website — all the companies listed there agree to abide by a code of ethics, so they only offer legitimate opportunities. Typically reps make a small investment to get started (this is a legitimate and standard practice), and sometimes pay a fee for the merchandise being sold. After that you can work as much or as little as you want, and see profit based on how much you sell.
Our first overlooked opportunity is selling your knowledge. In this instance, we are talking about creating a course or eBook that you can make available for purchasing online. Because of the automation available today, you may be able to put in the work once when creating your packaged information and then enjoy those checks coming in for months or years to come.
What’s the catch? None, really. Cash back apps act as affiliates for many online merchants, which means that whenever you make a purchase through one of the apps, they get a small commission — but then, they give you a portion of that commission as “cash back”. For example, if I buy a pair of Nike shoes through the Ebates app (or website) and spend $75, Ebates may get a $10 commission but then they’ll pass $7 back to me. It’s basically a way to get sale prices on stuff that isn’t on sale!
