Sounds like you are asking how to form a legal entity, which will allow you to avoid personal liability if your business is sued and provide you more favorable tax treatment -- I strongly recommend against operating as a sole proprietor.  So then, you must decide whether to form a corporation or a limited liability company (LLC). Either choice will require you to reserve a business name with the Secretary of State (SoS).  Once your business name is approved, you will then have to file articles of incorporation (if you are forming a corporation) or articles of organization (if you are creating an LLC).  Once you acquire your Certificate of Incorporation/Organization from the SoS, you should then obtain a Federal Employment Identification Number (EIN) from the Internal Revenue Service -- this can all be done online.  Once you receive your EIN, you can then open an operating account at a bank of your choice -- you should have your Certificate of Incorporation/Organization and your EIN handy because the bank will need copies of these.  You should then obtain a business license to do business in the county where your business is located -- you can check online to find out where you need to go in your county in order to make this happen.  Hope this helps.
