Participate in medical studies. If just the thought of this frightens you, know that the intensity of such studies varies greatly. Some studies ask participants (particularly those with medical conditions) to test treatments or medications that can have adverse side effects, but others ask participants to perform physical tasks with no lasting effects. If you are able-bodied and paranoid about keeping it that way, you can even participate as a control in a study at a nearby medical research facility or medical school.
Be someone’s virtual assistant. Not all administrative support staff work on site and take notes in-person at meetings. You can also help an executive from the comfort of your home by scheduling appointments, typing letters, ordering supplies, and preparing presentations. Zirtual may be able to connect you with someone who needs your help, though it may ask for a fee to get you started. You could also send some emails to companies near you offering your services.  
Not many people realize that Amazon actually has a pretty cool commission program. That’s right, Amazon will dish out commissions to websites that refer customers to its site. Join the Amazon Associates Program, create a website reviewing or promoting various products (with links to where users can buy the items on Amazon), and get a nice little cut if users complete an Amazon order.

Ask for a raise. If you’re unhappy with your compensation at your 9-5 job, asking for a raise is one way to beef up your bank account. Most employers offer an annual review of your work – which could be the perfect time to negotiate a higher salary or ask for better perks. If your employer doesn’t offer such an opportunity, it might be time to initiate a review yourself.


It’s not the sort of online money making opportunity that’s covered in glory, but everyone needs a set of eyes to make sure the numbers add up at the end of the year. Every business and most individuals need someone to help prepare tax returns, especially time or resource-strapped small business owners. The Income Tax School provides an array of training programs that'll certify you with tax prep in as little as 10 weeks, and once tax season rolls around you'll be able to charge an average of $229 per return as a freelance tax preparer with this side business idea, reports CNBC.
Believe it or not, this freelance bike messenger makes more money than some people glued to their office desks. You won't rake in a whopping $50,000 as this guy does by just doing this in your free time as a side business idea only, but you’ll surely get a piece of the action. Even Uber is trying out a blueprint for a delivery service, and companies like WunWun and Amazon are stepping up their efforts to expand same-day delivery, increasing the demand for more to jump in on this business idea. If you have a decent bicycle, those pair of pedals might just earn you a healthy side hustle income.
Similar to selling on Amazon, eBay is a place to make money selling just about anything you can think of as a side business idea, with the added excitement of using the auction selling model to sometimes get way more than you expected for that antique baseball card you picked up at a local street fair. To turn your eBay selling into a legitimate business idea, look for opportunities where you can buy in-demand products at a discount—and later sell them for a profit. Eventually, you can even take the lessons learned from your eBay store and build a full on blog or eCommerce business like what the team over at Gear Hungry has done.
