If you design a wildly popular app (which is harder than it sounds), you might be pleasantly surprised with the income they generate. Offering one or more apps at the iTunes or Android app store gives your creations wide exposure to prospects. And income can be generated by charging for the app, displaying in-app ads, or charging for in-app features and upgrades.
Find a profitable niche. Starting with your interests, write down as many niche ideas as you can. Think about topics people might search online. Ideas include passions (like surfing or body building), fears (like spiders or speaking in front of crowds) and problems (like getting out of debt). Do keyword research to see it others are interested in the topic. Find out if a domain name is available that matches the keyword 100 percent. 
Since work hours are less regulated in telework, employee effort and dedication are far more likely to be measured purely in terms of output or results. Fewer, if any, traces of non-productive work activities (research, self-training, dealing with technical problems or equipment failures) and time lost on unsuccessful attempts (early drafts, fruitless endeavors, abortive innovations) are visible to employers. Piece rate, commissions, or other performance-based compensation also become more likely for telecommuters. Furthermore, major chunks of per-employee expenses are absorbed by the telecommuter himself - from simple coffee, water, electricity, and telecommunications services, to huge capital expenses like office equipment or software licenses. Thus, hours spent on the job tend to be underestimated and expenses under-reported, creating overly optimistic figures of productivity gains and savings, some or all of those in fact coming out of the telecommuter's time and pocket.
Telework centers are offices that are generally set up close to a majority of people who might otherwise drive or take public transit. They usually feature the full complement of office equipment and a high-speed Internet connection for maximum productivity. Some feature support staff, including receptionists or administrators. For example, a number of telework centers have been set up around the Washington Metropolitan Area: 7 in Maryland, 8 in Virginia, 3 in Washington, D.C. and 1 in West Virginia. Telework centers allow people to reduce their commute yet still work in a traditional office setting. Some telework centers are set up by individual companies while others are established by independent organizations for use by many organizations. Telework centers are attractive to people who do not have the space or inclination to work from home. They offer employers the ability to maintain a more formal structure for their workforce.
Robert said he did an average of 4-6 of these gigs per year for a while depending on his schedule and the work involved. The best part is, he charged a flat rate that usually worked out to around $100 per hour.
