For those casting about ways to do this there are a lot of options. Too many to cover in a single post.
For small dollar commerce you can get paid to take surveys. I used Prolific, which is for academic researchers to gather data for their studies, but it is not available everywhere. You will usually get less than a dollar per survey, but they are short. A quick google search will reveal any number of small dollar options that companies are willing to pay to rent your eyeballs and attention span. Attachment below.
For mid dollar commerce, if you have a bachelor's degree you can sign up to help students by answering homework questions. I did this for Study.com for a few months, they pay $5/answer but it was college level stuff and worked out to about $8/hr once I got good at it because the answers need to be detailed. It does have the added benefit of helping you brush up on your old academic skills if you feel like you need it.
Finally, for full-time commerce, if you have a bachelor's degree and are a native or near native English speaker, you can get an English as a Second Language certificate and do online tutoring. This can pay anywhere from $15-50/hr depending on your qualifications, experience, and any sort of niche that you can fill (IELTS, STEM, Business, etc). I've heard rumor that it can get higher than that but this seems to be the market consensus rate. I haven't done this personally but I have known people who did it full-time and made decent money.
I sell physical copies of my music online. Sometimes I sell t-shirts and miscellaneous merchandise as well, but they sell better in person when I play live than online. Here are the receipts for the last couple months.
Hi Kyle, could you elaborate more upon how the CDs are burned, where they're shipped from and how involved you are in getting the CD from point A to point B? If you're doing all that, then it's a fit for this BB (per my understanding of Paul's brain). If a service does all that and you just see the money roll in, then it isn't a fit for this BB.
