Can I form a LLC by myself, or do I need partners?

LLC is really the simplest form of a corporation, and yes, unless your state is totally bizarre, you can establish it as a sole proprietorship with no partners. The main thing the LLC does is separate your personal liability (as in when DBA) from your business. Try LegalZoom.com. Also, in my county in NC, it is very easy to do through the courts. They have an LLC formation information packet with necessary paperwork. Call the courthouse before you spend any money. They can't advise you, but they likely have the necessary forms....you can always amend later....good luck
