Dear Sir/Madam,
I told you in my earlier answer that you can either file your tradmark registration application online by visiting this site http://www.uspto.gov/teas/index.html or if you need paper form then you can call this number 1-800-786-9199 (or 1- 571-272-9250) and they will send you the proper forms.
Remember this is for registration of your "SLOGAN" but NOT for registration of your business or for license to open your business. If you need help to find out how to get license for your business then you will have to post a separate question because your present question is about "Slogan" not about getting business license.
If you have any other question, please feel free to ask.
