If you’re a fitness buff and have the right combination of charisma and business sense, working as a part-time online personal trainer can be both physically and financially rewarding. Once you build up a reputation and client base for yourself, it could easily turn into a full-time endeavor for you. Check out a few of the top fitness blogs and observe how they make money online from their content sponsorships, affiliate earnings and product sales.

Choose your niche and check for demand: The golden course combination is when you can find an in-demand niche that aligns with your skills and unique experiences. A great way to do this is to use Google Trends, Google’s Keyword Planner and other key blogging tools to do keyword research and look for average monthly search volume for keywords related to your proposed course content. Are people actively looking for high-quality information about this subject? Of course, if you’re already creating content for a blog, coaching service, or a site like Medium, you can test demand this way for free just like Bryan did.

Now, it’s time to start creating and uploading content. Make sure you’re using a high-enough quality camera (most smartphones will work but I’d suggest at least having a tripod so your footage isn’t shaky), but don’t worry about being perfect at first. The beauty of YouTube is that you can continue to test out different content and styles as you find what works for you. Instead, stick to a regular schedule to build up your subscriber base.
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. 

Blogging is something that requires patience, persistence and discipline. It may mean writing everyday for over a year before you really start to see any money from it. There are exceptions to the rule, but from my dealings with other bloggers, it seems to be pretty common to spend one or even two years building your blog, your brand and your authority, before making any serious amount of money.
Every year, hundreds of millions of documents are notarized in the United States: wills, mortgages, citizenship forms, handgun applications. While for decades, this has all been done in person, there is a budding crop of sites that allow notaries to take their services online. If you’re already a notary, you can sell your services online. Or, if you want to get started, check out the National Notary’s checklist for becoming a certified notary.
5. Fiverr – Fiverr is a great place to make a few bucks or spend a few bucks if you need some of the services people offer. Basically, everything is $5. You either pay $5 or charge $5. They call them “gigs.” You can offer your services however you choose. If you sell art and you’re fine selling pieces for $5 each, that’s a gig. If you’re a graphic designer and you want to offer your services for $10/hour, simply offer a 30 minute gig. If they need two hours of graphic design, they pay you $20, or $10/hour by buying four gigs.
