One step at a time. You must first decide what type of business you are interested in. It should be something you are interested in and have some knowledge of. You should formulate a budget. What capital do you have to get the business up and running? You should form a business plan to help guide your thoughts and actions. If you will be seeking financing from outside lenders they will insist on examining your business plan. The amount of money they lend you, to a large degree, depends on the feasibility of the business plan. Make sure you do some research in your community to see if a business license is needed. Also, depending on the type of business you are starting, other regulations and laws may be applicable to your enterprise. Do your research first before spending any money.
