Hope all goes well for you.
Finding a good Medium takes time and patience. In the UK many Spiritualist Churches/Temples have development circles, and there are also specialist training centres such as The Spiritualist Association of Great Britian
and I assume the same is true in the US.
Equally just going to an open demonstration of Mediumship can produce a contact too, as I found out when I went with my wife to one. I plan to cover it in detail in a future article on the Pagan page. I was impressed not only with the accuracy of the information, but the professionalism of the Medium who kept followed his training and seemed to transcend his own personal beliefs
