Find something that you can make cheaply and sell expensively. Then make lots of them and sell lots of them.
Your best bet is dealing with your local public officials. Many communities have some sort of small business administration that helps people like you work through the many steps needed to successfully start and run a business. Look through the yellow pages and do Google searches. In addition, many local county Extension offices can give guidance with small business.
