I see a comment made by Stella including some freelance sites. This does work. I use oDesk and it’s been a big help in bringing in a little extra money. I also agree with some of the other comments that mention people should think of or view more ideas of making extra money, because it really is possible to make extra money instead of just sitting around moping about not having money to pay the bills or buy something special.
Today, if you're at all serious about succeeding in any endeavor, whether online or offline, you have to deliver enormous amounts of value. Yes, you have to do the most amount of work for the least initial return. This is especially true online. Why? Because it takes time to build authority and create an audience, two primary ingredients necessary to succeed in the wonderful world of commerce on the web.
Most of these ideas can be scaled up to meet the needs of more customers and can have a huge impact on your financial prosperity. People who land on this page are looking for ways to make money right now. Some of these may be cliche, but that’s because they are proven. You can start making money tomorrow with most of these ideas. You can then, overtime, scale/pivot these active jobs into more passive entrepreneurial efforts. For example, you could start bar tending tomorrow and then one day become a bar owner or beer/wine producer or event planner or whatever you dream up. The point is to get going with something and look for ways to add more value to more people.

 @dasjung No doubt! I know this and you know this, and any other highly skilled and educated designer will also know this. But what about the customers? The people who are looking for a logo design with much consideration of price in this economy.  Knowledge and talent expect the monetary reimbursement it deserves, but unless everybody has a trained eye to recognize it, they just aren’t going to dish out the money for it. That is the point I am trying to make. It is like calling the neighborhood handyman instead of  a high cost plumber to fix a small leak.

I really like the idea of writing poorly written ads. It seem like it can be easy and you can make a small profit. I know that use to work at a school and we got our extra money from writing grants. People can write grants to start a business so I am in the process of trying to write my own grant to start a community program for teens. its a litte extra money and I still get to do what I love. If you have any kind of hobby you can prob. turn that into some income if you can get creative. Good luck

 @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.
6. IZEA – IZEA works in addition to a blog or on its own. You get paid to blog, tweet, take photos and take videos. The pay is mostly based on your following, so if you want to make money with your tweets, you’ll need to grow you Twitter following.  Likewise, if you want to make money with blogs, you’ll need substantial blog traffic (more on blogging below).

…Marketing an eBook is definitely the hardest part. Ebooks have exploded in popularity and the market is unfortunately saturated with crap from people who thought they could write a quick eBook, put it on an affiliate network, and make millions. However, if you CAN find a good way to market (or possibly have others market by having it listed on affiliate networks) then an eBook can be a great way to make some residual income.

The stuff you can’t sell online, you could sell from your garage on the weekends. Many neighborhoods plan annual or bi-annual yard sales. If you have items to sell, this is a great time to do it as the neighborhood as a whole can bring in a lot of traffic and help you perform better than you would on your own. If that’s not possible, consider partnering up with a couple of families in a popular neighborhood.
Hunt for under-priced used books that you can sell online. Download an app that reads ISBN numbers so you can scan the barcodes on books. This will pull up the book’s current price on Amazon so you can see if it’s worth trying to resell it. Then, visit used book stores, thrift stores, and garage sales to look for high value books. Post the books for sale online using sites like Amazon or Ebay.[9]
