Commercial use requires 'releases' - editorial use doesn't. Stock photos can be sold for commercial (eg, marketing) or editorial (ie, journalistic) use. You'll have more opportunities to make cash if your photos are available for both, but photos containing people or property (including branding and logos) need signed releases to be sold commercially.
If you have good smart phone having good picture quality then you can click the historical or nature pictures or the one which are in demand and using some editing application you can enhance those pictures and promote them. You can easily sell them at your own fixed price. "Foap" and "Dreamsite" are the mobile applications that offer the same service.
Re-skinning apps is a pretty simple process. Basically, you purchase/create a template, change the graphics of the template, and then sell the app. The entire process will take between 1 and 3 hours depending on your experience. After having re-skinned apps for over a year now, I’ve found that the typical re-skinned app sells for between $100 and $300. However, I’ve had single re-skins that have sold for over $2,000! That’s a lot of money for an app that took just 1–2 hours to make!

If you’re asking, “how much do affiliate marketers make” – well, Michelle Schroeder-Gardner makes over $50,000 / month from affiliate marketing. She is her own boss, and lives the dream life (on the road) with her hubby. She’s recently released a course on affiliate marketing, right from the what-it-is to the how-to-do-it (legally) – and the results her students (like me) have seen so far have been incredible.
Before jumping into starting an affiliate marketing business, learn all that's involved in making it a success. More importantly, if you decide to pursue an affiliate marketing business, or want to add affiliate marketing to an existing business, understand that it's not fast, automatic, nor without effort. Like all home businesses, ​you need a plan and daily involvement to make money with an online affiliate marketing.
To get started with Amazon affiliate marketing you will need to sign up with Amazon Affiliates. Then subtly market products on your site that are relevant to your niche and will be of interest to your audience. Make sure you only endorse high-quality products. If your visitors make a purchase on your recommendation but are not impressed with the item, you could quickly lose followers.

Rose and others looking for employment this summer: Retry the babysitting idea. Summer is a good time to babysit. Maybe volunteer a few times first and then use those families as references. Tell everyone you know that you are available to babysit. Use email, Facebook, fliers, word of mouth. Also try offering a set time every week, like Tuesday evenings form 5-9 pm in your home. Parents know they can drop off their children without calling ahead. They really appreciate that. It takes time and persistence to get the word out, butit can be done!
