I’ve just started a single member LLC in SC, and I’d like to contract with a company in Florida. I will be working predominantly from SC remotely, but may end up in FL for an onsite every once in a while. Do I need to _also_ set up an LLC in Florida to make this work or is my SC LLC sufficient? If yes, do I need to do this in all 50 states if I want to do business with entities in each, or how do individuals acting as contractors handle that?
