Hi! That is great question.
A wonderful place to start is Meetup.Com they have groups where you meet on the phone and in person and cover all most anything.
I know they have groups for psychics on how to develop your abilities as well as groups for people who want to hone their psychic skills. These groups are free and most likely they have one in your area.
I think that is great that you want to follow your passion and help people. Let us know how it’s going. I wish for all the success and happiness in the Universe!
