Nice writing style Ben. I’m finding out very quickly that to make any money writing, you have to read, read, and then read some more, no matter how smart you feel you are on a subject, before writing your first sentence. I have always been a fan of multiple income streams and am thrilled by the ideas of proofreading, editing, blogging, freelancing and transcribing. Having spent one of my careers doing just that for a large corporation, it’s a perfect fit, but now I can get credit for my work, thanks again for a great article.

Display. Just as in any retail operation, the way you display your wares will greatly impact your sales. Produce should be placed underneath a cover to protect it from the sun, but be sure to allow at least seven feet of head room. Display your prices prominently, and clearly identify the things that make your product special. Personalize your stand with signs to inform your customers.
Raise your hand if you love the idea of earning extra income or ditching office life to learn how to make money at home. Well, you're not alone. According to a 2017 telecommuting report by FlexJobs, the number of U.S. employees who worked from home at least half of the time has grown 115% in twelve years, from 1.8 million employees in 2005 to 3.9 million in 2017.
Another obvious option is for people who enjoy writing. There are countless requests on sites like Elance for all different types of writing. Polish your writing ability and then start bidding on some of these writing jobs. At first, you'll be doing this a few hours a week, but over time, you can build up a dedicated clientele and make a full-time living off your writing.
Do what you know. There are many programming languages out there on the market. When you do freelancing, you should remember that clients pay you to solve problems. You are not paid to learn new tools and languages. It is always good to expand your programming skills to learn other languages. However, you should only bid for the job that you are confident with.
One thing, though, there is a big difference in making an app for Android and an app for iOS, and that is the fact that making an app for Google Play costs just 25$ one-off, making an app for iOS costs 99$ a year, so if you are making an app for iOS, I will recommend you to be a bit more confident about the way you will make money by your app, than if you are making an app for Android.
Speaking of teaching, even if you don’t have a teaching degree or current certificate, you may be able to make money teaching English online. This is a great side gig for those working a full-time job. The scheduling is flexible and you can work in the early morning, evenings and on weekends. And the pay is pretty good, too! Some ESL tutors are paid up to $21 per 40-minute class. A few companies to consider:

FlexJobs, a search site for the best work-at-home jobs, reported in their The State of Remote Jobs survey that, as of 2017, 43% of U.S. workers now work remotely — even if it's just a part-time side hustle to supplement their income. For remote jobs, you'll need a computer, some basic skills, and a can-do attitude. And yes, even nurses, teachers, editors, or graphic designers can find countless of opportunities for work from home jobs.
