If you do well with your business, you may want to incorporate it. There are many advantages gained by incorporating. For one, if (and this is a BIG if, but you never know), if you are ever sued, your personal assets will be considered separate from your business assets. On the off chance that anything like that ever happens, you will be immensely thankful that you incorporated.
It works the other way too, if you are ever personally sued, all your business assets are safe. Legally, you and your corporation are two entirely separate entities.
Another reason for incorporating is to save money on taxes. Talk to an accountant about the different ways to incorporate
