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. 
Working from home takes a lot of self-discipline. Before you become a remote worker, make sure you have a good system for keeping yourself organized and on task. Use whatever works for you – make a bullet journal, organize your duties on Trello, keep a detailed Google Calendar with Calendly for setting meetings. Just make sure you have a self-management scheme that keeps you going. I really like the new Focused Collection from Erin Condren.
Whether it’s an important consumer application, a specialist app to solve a particular niche problem, or even a time-wasting game you can play on your phone, you can create a massively successful business if you build software that helps people. (Look at the rise of Slack—the team communication software that went from side project to billion-dollar company in just 2 years.)
If you are a creative type, then you could make money online by designing and selling crafty products on Etsy. Etsy sells a range of beautiful and original items from independent suppliers. Categories range from jewelry, clothes, and accessories, to art, collectibles, and vintage. So if you have some stunning crafty creations, Etsy is the perfect platform from which to sell from.

Mow lawns or plow driveways. If you’re willing to mow yards or shovel or plow snow in the winter, you could easily start your own snow removal and lawn mowing business on the side. While you can usually find work by reaching out to your local community via word-of-mouth, flyers, or online message boards, the website Plowz & Mowz allows you to set up an online profile and reach more customers in your area.
Once you’ve gathered a list, put together a template outreach email (as you’ll be doing this over and over) that’s short and clear with expectations. Tell your potential interviewee who you are, what your podcast is about, and what you’re asking of them. Do a few test interviews with friends and family to make sure everything is being recorded at the quality you want and then book your first episode.
Tools & Resources: I’ve written a pretty comprehensive guide on the best web design software that covers both free and premium software packages. If you’re serious about becoming a web designer, then I recommend purchasing the full Adobe Creative Cloud Suite. At $49.99 per month, this is probably a bargain considering what you can achieve with this set of tools.
If you have a fondness and talent for taking pictures you can make extra money online by becoming a stock photographer and selling your images to a stock photo company like ShutterStock or iStockPhoto. You’ll get royalties every time someone licenses an image you’ve submitted. To really be successful, build your own photography website to be able to showcase your portfolio and start getting higher-paid private corporate work.
If you love to travel and find yourself randomly searching for airfare sales or browsing Lonely Planet, why not carve out a niche for yourself as a private travel agent? My friend, Mark Jackson did just that, making extra money online with his travel consulting side business. Start with word of mouth recommendations from friends who know they can count on you for the cheapest flights, and then move on and create a Facebook or LinkedIn group to invite people who want to stay on top of the latest deals. Eventually you could spin this into a full-time consultancy teaching people how to make their dream trip a reality.
