Try your local spiritualist church, or word of mouth. I had a recent tarot card reading via a flyer through the door. Pure chance ..... or was it?! It was brilliant and I recommended her to a couple of friends, one of whom had a reading over the phone. They both thought she was great.
One of the things she told me was how unhappy I was in my job, how I had all sorts of skills I wasn't using and was really accurate about how I was feeling. She was spot on and there's no way she could have known that. She went on to tell me not to worry that I'd be changing jobs. Three weeks later I had a phone call out of the blue from our Senior Manager asking me if I wanted to move to another unit.
