Who do I talk to about a business license? -

I need to know where to go to/who to talk to to find out if I need a business license for an online business of products I make and if so how I need to speak to them about how to acquire one. I realize whoever this is has to be in my town but who in my town do I talk to? haha.

Talk to the Small Business Administration in your area. They will help you file all the appropriate paperwork with the proper authorities.
