Hi Adam and welcome
Being here in the UK, I don’t know, what structure that is needed in the USA, yet here in the UK, there is no formal licensing, which means, anybody can set up a NLP, hypnosis, life coaching company, with out to much trouble, so I am assuming you could probably do the same, yet that means, you lake any credibility in many ways and would have no support from a net work of people on the same path. And I am sure someone will be able to give you the lay out much better then this.
The 2 Links below are to Meta-Coaching which is one of the most up to date Coaching systems, in the world, and it is hosted by Michael Hall, who is by far one of the most gifted NLP educators on the planet, and has done an incredible Job at adding academic credibility, to NLP, and the 2nd link is also to Michael Hall’s Neuro-semantic wed site, this as little to do with coaching yet the articles are a delightful read, and will show you just how this Guy can deliver, I am a big fan Of Michael Hall and have about 20 or so of his books,
Getting back to coaching, the meta-coaching web site have a number of free audio files to down load, that will give you some ideas, of where you might what to be heading.
One book I would recommend, would be The Life coaching Handbook By Curly Martin, will give you a good foundation, of what your responsibilities with regards to the coaching session.
