Overall good ideas, but we need to define the idea of ‘fast 100 bucks. Swagbucks is pretty slow as an income resource and it would take a while, not to mention selling stock photos is not something you do in 2 days. I tried this 4 years ago with my close to pro’ photos and it took days to set up a small portfolio there with some outstanding work and yet made no sells.

What are the best ways to make money right away? While a search online when you're in need of some fast cash will produce millions of results, not all will be legitimate. It's up to you to filter through the so-called noise. These 32 strategies will help put you in the black, even if it's in a very small way. Once you are, resume planning and focusing on the bigger picture.
Opening your shop, listing products and prices takes less than 30 minutes. It costs $0.20 to list one item in your shop for 4 month (or till it sales) and Etsy takes 3.5% commission from each sale you make. Mind that fact when setting up the prices. Shipping costs are either to be covered by you or by the buyer (you can set the rates depending on the buyer’s’ location e.g. free shipping around US; $10.99 shipping to Europe).
I first learned about you when I downloaded your free e-book, How to Make Money – BLOGGING, via Amazon Kindle. It was a sure one-sitting kind of book but is very meaty. I got all the wonderful ideas from your book and finally decided to visit your website to harvest some more inspiration. I am so glad my path was directed here because I also have just started my incognito blog.
Regardless if you need to earn some fast cash or we're just talking about making money in the grand scheme of things, there's an important psychology that needs to be mentioned before getting into the strategies. If you study Freud's model of the mind, you'll discover the Psychic Apparatus. It's the three-part construct in your mind that controls all of your behavior.
Stay rich. It's hard to get rich, but it's even harder to stay rich. Your wealth is always going to be affected by the market, and the market has its ups and downs. If you get too comfortable when times are good, you'll quickly drop back to square one when the market hits a slump. If you get a promotion or a raise, or if your ROI goes up a percentage point, don't spend the extra. Save it for when business is slow and your ROI goes down two percentage points.
Ebates is another cash back app, similar to Dosh, and right now they are offering a $10 signup bonus. There’s no rule saying you can’t have multiple cash back apps, so why not sign up for a couple just so you get the bonuses? Once you get your bonuses, then just use whichever app gets you the best deal on your upcoming purchases. Easiest money ever!
I’m really torn here. As a writer, I sympathize with you. I’ve looked again and again into freelancing, and consistently find that the rates other people are willing to work for make it an insulting waste of my time. (Like, $10/hour is what a 15-year-old babysitter makes, not a professional writer.) On the other hand, you really can’t ask others to not compete with you. On the plus side, in my (limited) experience, you do get what you pay for most of the time. My sister had a less-expensive wedding photographer, and she was definitely less than happy with the results. So …
Don't put all your trust in Social Security. While it's a good bet that Social Security will continue to work for the next 20 or so years, some data suggest that if Congress doesn't radically alter the system — either by raising taxes or reducing benefits — Social Security won't be available in its current form. It is probable, however, that Congress will act to "fix" Social Security. In any event, Social Security was never designed to be the only resource for retirees in their later years. That makes it all the more important that you save and invest for the future. 
– Project Payday is one of those sites that has testimonials of people who have earned thousands of dollars by getting paid to get trial offers. I’m not saying you’ll earn thousands, but it is legit and you can earn some extra cash. They assume that by paying you to do a free trial, you’ll either like the product and purchase it, or forget to cancel the trial and get charged for it. If you can keep track and cancel before you get charged (if you don’t want the product), then this is a great site for making some money.
Become a proofreader. All kinds of businesses hire professional proofreaders to look over their copy and content for errors before they publish. This side hustle is one that could work for nearly anyone since you can work from home provided you have a computer and an internet connection. You can find online proofreading jobs through websites like Indeed.com and FlexJobs.com
Rover is a dog walking and pet sitting website that is always looking for qualified dog walkers in cities all over the United States. So when you take your pup on a walk, you can also take a second (or third) dog with you and get paid to walk. 30-minute walks fall in the $10-30 range. With a neighborhood route, that can add up quickly! You’re just a short application away from getting started.
Websites like Care.com connect parents with babysitters. The company does all the background checking and other due diligence to put parents' minds at ease. Of course, you can appeal directly to people in your personal network, but if you're looking to generate recurring revenue sign up with a site marketing to parents looking for child care services.
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.
