Sully no disprespect but have you looked at all options
ICHP based in Cork are the recognised body for hypnosis training, they are well regarded and are the only legit body in Ireland
Regarding NLP are the best, they are certified and recognised by Richard Bandler.
I would suggest you think hard about this one. You will need a certificate/diploma to practice, they will help you with insurance etc
Hypnosis is great and can really help, i would say get a few books read up on it, talk to others, contact ICHP. In order to be credible you need a certificate behind you, people will not have faith in you if you have just learnt stuff from a book
I would also look at the whole NLP area, to me it is more meaningful, basically looks at the present and the future, rather than dwelling on the past and the present. again depends what your thoughts are on counselling etc (although nlp is not counselling) it can achieve fantastic results very quickly
if you want to chat pm me and we can talk
