Please don't use these sorts of services. Even if you technically can be savvy and avoid all their fees and things, they're dishonest and try to tack them on constantly for things you may or may not need (eg. for making them a registered agent, unnecessary credit checks, etc.). Even if it is possible to make it work and avoid most of this, don't support their business model. Chances are you'll pay more in hidden fees than just learning to do it yourself (which is probably find if you're just filing an LLC, not fine if you need advise on whether an LLC is the right business vehicle for you) or the few hundred dollars a lawyer will charge you to file an LLC.
