my production company/label

Hey my beats are starting to get known local so I copyrighted everything to me I didn't get a business license but Iwent the the Secretary of the state and got BeatStop Productions INC. Incorporated got my tax ID so officially I'm an S Corporation and I got a business checking account setup is there any licenses I need to sell beats? Also I'm putting together an Indy label too any knowledge on the legal shit of that?

Future Producers, got a lot of this info in their industry talk forums.
