Teach. If you're an expert in a certain subject, see if the community, local colleges, or even the private high schools in your area are looking for a teacher in your field. If you can pick up just one night class per week, it can make a difference in your income. Though you'll need certification to be a traditional teacher most of the time, to teach part-time you may only need a master's degree and proof of your expertise.
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 and Google’s Keyword Planner to 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.
My local Craigslist.org is the first place I go to sell something. It's best for items you think will appeal to everyone (therefore justifying the smaller audience) and large items that can't be shipped. Craigslist.org is great for taking your yard sale items online for local sales. For example, a friend recently bought two fans from people that live close to him. These one-off type items do very well on Craigslist. Just remember to use common sense and be safe out there.
Running a coupons website can be very lucrative. Find a coupon niche, select a WordPress coupon theme, and then display relevant coupons on your site. When your audience uses the coupon codes or discount links, you will earn an affiliate cut, for example, you could set-up a site dedicated to iHerb Coupons or add a page to your website with Web Hosting Promo Codes. Coupon websites are quite high maintenance as they need to be constantly updated with new offers. However, if you build up an engaged audience and allow them to post coupons and discounts they have found themselves, then quite quickly your workload will reduce.
Rover is a dog walking and pet sitting website that is always looking for qualified dog walkers in cities all over the United States. So when you take your pup on a walk, you can also take a second (or third) dog with you and get paid to walk. 30-minute walks fall in the $10-30 range. With a neighborhood route, that can add up quickly! You’re just a short application away from getting started.
