If you decide to operate your own business you may not necessarily have to have a license, but it is always a good idea to separate your business assets or property from your personal assets or property. A market is a public place where buyers and sellers make agreements to exchange goods or services for payment. In order for the market to be efficient or successful the good or service must reflect the true cost associated with providing the good or service. If your prices were much higher than the normal, your service would not reflect the true cost associated with providing this service. Identify the type of person who would buy your good or service.
Marketing research is a good start.
After you have created your product or service, you can design a survey asking questions about your product or service. You can determine your potential customer base by collecting and analyzing information about how your customers will react to your product or service. By conducting research, you can gather information about groups of people characterized by age, income, sex, education and occupation. For example if you started a pet sitting business it would be counter productive to market to people who did not have pets. The above examples will help you determine your customers wants and needs.
