If you live near a university, there are likely all sorts of research studies looking for participants. While I was an undergrad at Virginia Tech, I got paid $500 to participate in a 6-week dietary study. The study provided all my meals and paid me, but I had to eat a 5,000 calorie diet of 50% fat for 6 weeks, plus I had multiple muscle biopsies, urine/blood testing, etc.
Mechanical Turk is Amazon's take on micro-jobs. These are small miniscule-jobs that you can do for other people, which they call HITs, or Human Intelligence Tasks. These are super simple tasks that anyone can do. Some examples are listing off some URLs with certain kinds of images for one cent, or recording a few phrases with a microphone for 6 cents.
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.
If you can find and restore items like furniture and appliances, you can make a substantial amount of money. You can acquire the items on Craigslist, or even at garage sales or estate sales, restore them, and then list them for sale on the site. You may also be able to market certain items on eBay, particularly if they are small, unusual, but high in price.
How much will you make? I think my best month with Google AdSense was almost $5,000 over the last ten years. That amazing month blew my mind since it was actually near the beginning of my blogging journey. When you go from making zero to $5,000 in a month, that will rock your world. For me, it also got me even more excited because I knew there were other ways to monetize.
