If you have a good idea for an app, and the skills to create it, then producing your own premium app can be profitable. However, with so many free apps available, it may be hard to convince people to pay. If you want to go down the premium app route, consider having a basic free version to encourage people to download the app in the first place. You can then provide the option of upgrading to a premium plan once users realize how useful the app is.

Travel blogging is a hard industry to break into. However, the rewards can be worth it, and let’s face it, who doesn’t want to be paid for traveling around the world! There are numerous ways to monetize a travel blog, but affiliate marketing should predominantly be your focus. On your blog, promote hotels, tours, equipment hire services, flights, and anything else travel related. Then take a cut of the proceeds as your audience books their holidays based on your recommendations.
Mystery shopping can be a way to earn a little money moonlighting close to home. Also known as secret shopping, it involves pretending to be a regular customer at a business and then providing feedback on your experience to the company that hires you. That company then aggregates the feedback of multiple mystery shoppers to let the business know how it can improve. However, these types of jobs can also be the bait for work-at-home scams, so you have to be very careful and know the signs of mystery shopping scams.
Again, if your blog has a large reader base, then businesses may be interested in paying you to review their services or products. Not only will you get a free trial using whatever these businesses are selling, but you will also get a fee for writing them a review and posting it to your site. Paid reviews (and other paid and sponsored content) can be big money, so advertise this service on your contact page to generate business.

If you're an exact size 4 or the perfect size 8, fashion designers need you to try on their designs and give feedback on what does and doesn't work for your shape. The pay is great—between $2,000 and $3,000 a day—but you need an agent. MSA Models (570 Seventh Ave at 41st St; 212-944-8896, msamodels.com) is the gold standard and holds open casting calls (show up at 10am on Tuesdays). Mary-Evy McNenny, a 51-year-old Upper East Sider, has works as a fit model for Lafayette 148 and Ellen Tracy—and she admits it's not easy. "You cannot lose or gain weight. Just a few pounds and things won't fit the same," she says. "I weigh myself every day. When I go on vacation, I bring a scale in my carry-on bag."
As for other tips, all I can say is “a penny saved is a penny earned”. If you are running out of ideas to make money, start saving. Some quick “low hanging fruit” tips to save some quick cash include – switch to MetroPCS or Boost for cellphone (I only pay $20/month), switch auto insurance to Insurance Panda ($25/month), and start using GasBuddy (saves me like $100/month at least. I drive a lot).
