Competition to get into top universities is as tough as it has ever been, so nervous parents are willing to pay handsomely for tutoring for their kids. You need an area of expertise—math, and specifically SAT math preparation, is always a favorite—but almost any subject will work. If you know how to market yourself locally, you can take advantage of parental paranoia and make money by tutoring right in your own home, or at a local library or coffee shop. Just make sure to do your homework on your local market in order to set prices and know which areas of expertise are most desired by parents in your area.
Notice the "may be". Although there are many entrepreneurs that make an excellent living at home in professions such as consulting or information technology, the home businesses listed here are not generally big money makers. They are however, legitimate businesses rather than "make money in your sleep" or any of those other phony work from home schemes.
Another idea someone could do from home is to start a service or write a software program that scours local ad listings (like craigslist) for a particular used item a person wants to buy. They have services like this for new items, but not used. I know others like me who are keeping their eye out for something used (like a canopy king bed!) but don’t have the time or inclination to search for it every day.
The main driving force behind the growth of home-based businesses is the increasing capability and availability of computer and communications technology. Powerful yet affordable home computer systems equipped with modems allow people to send and receive messages, transfer data, and conduct research from their homes, largely eliminating the need for those employed in such endeavors from having to commute to a place of employment. Similarly, sophisticated software programs offering applications in desktop publishing, database management, financial management, and word processing enable one individual to do the work formerly handled by an entire support staff. In addition, the widespread use of cellular phones, pagers, voice-mail systems, and toll-free telephone numbers has enhanced the ability of home-based business owners to remain connected to the outside business world. Rapid improvements in technology have enabled large numbers of home-based business people to earn the same income they could at a regular jobs while also gaining a number of lifestyle benefits. Another important factor in the growth of home-based businesses is the transformation of the American economy from a product orientation to a service orientation. Since service businesses generally have no need to store inventory or run production machinery, they are less disruptive and more adaptable to a neighborhood environment.
Concentrating all marketing efforts on a small but specific and well defined segment of the population. Niches do not 'exist' but are 'created' by identifying needs, wants, and requirements that are being addressed poorly or not at all by other firms, and developing and delivering goods or services to satisfy them. As a strategy, niche marketing is aimed at being a big fish in a small pond instead of being a small fish in a big pond. Also called micromarketing.
