I’m a huge fan of blogging because I love writing and connecting with people all over the world. To give you an idea of what is possible with blogging, DollarSprout.com is part of a group of blogs that routinely brings in over $100,000 a month in revenue. While it takes time to build your blog up to that income level, you can get the initial set up done in under 30 minutes (no experience needed).
Mechanical Turk: Amazon's Mechanical Turk is a resource for doing human-intelligence tasks, or as the site commonly refers to them, HITs. You get paid a very small fee for any given HIT and you'll need a good deal of volume to make a substantial amount of money. But it is a resource you can use in your spare time to generate a small income online. 

21. Facebook – Facebook swap shops are great for selling things locally. It’s like CraigsList, but a little easier. You simply search for swap shops in your area and ask to join the group. Once you’re in, take a picture of the item, write a quick description with the price and post it. It doesn’t get much easier than that. You can generally expect to get about what you would get at a yard sale, maybe a little more.

Many banks will give you a cash bonus just for opening an account with them. Talk about easy money! Banks are in tough competition for your business and will pay $100, $200 or even $300 just for becoming a customer. For example, right now Chase Bank is offering $200 cash for opening a checking account, and then another $150 cash for opening a savings account. Certain qualifications must be met but if you do qualify that’s one easy way to earn $350 cash! Collect $350 cash with Chase Bank If you click this link and make a purchase, we earn a commission at no additional cost to you.
 @Philip Taylor I was merely using medical science as an example profession. It’s quite obvious that you don’t have any professional courtesy and downplay professions in which you don’t understand. Logo design isn’t just logo design. I don’t know what the profession of a public accountant entails, or a lawyer perhaps, so I’m not going to give advice on matters that I don’t especially have knowledge in.
Find items that you know are selling below their full value (either online or through a deal website like SlickDeals.net), discount stores (Marshalls, Ross, etc.) buy them and sell them for more on eBay or Amazon. Once you find your product niche you can set up a system. Don’t read over that too quickly. You need to find a particular product or niche to really make this work. Otherwise, you’re met with different shipping costs, always trying to figure out new margins, etc. Don’t try to be everything to everybody. Try to be good in one particular. Maybe it’s a product you’re passionate about such as selling trucker hats.  🙂 Click here for more on this idea.
Try flipping houses if you have experience with making home repairs. As you may know from watching popular home improvement shows, flipping homes involves buying up a lower valued property that needs work, and then fixing it up for resell. To get started, you’ll need to have financing either through a bank a partner. Then, you can buy a property that’s priced below market value. After you renovate the property, you may be able to sell it for a profit.[10]
