You will need a lawyer who can help you decide whether a corporation or limited liability company (LLC) is the better way to organize your business, and prepare the necessary paperwork. He will also advise you on the best way to prepare to expand your business when the time comes, where to incorporate (each state has different advantages and disadvantages) and how the different stakeholders should relate to each other. A good specialist in Business Organizations can also advise you on what structure you should use to maximize your personal protection and what steps you and the business must do to ensure that protection holds under stressful times.
