Roark, just an FYI, as the owner of the business, you'll create nexus in your state of residence for the LLC.
IE, your status as the guy running the show will put you on the radar screen.
Also, if you state taxes your income (and it probably does) your LLC will appear on your federal tax return and so need to be included with your state return, too. An LLC is (by default) disregarded as an entity separate and apart from its owner.
