I, for one, believe in Guardian Angels, though I tend to think of them more as guides. Spirits or entities that help us along the way in life, the life between lives and beyond. I had an 'imaginary friend' when I was very young and I know in my heart that it was my guide. Just recently I asked him, yes it is a he, for guidance through a dream. That night I had a powerful dream that woke me in the middle of the night and was directly related to the situation I needed help with.
As for your situation, it depends on if you trust this person, hard to do on-line I know, and how much you believe or want to believe. There is another way to find you 'Guardian Angels'. Ask for them. Sit quietly, clear your mind of distractions, and ask them, or he or she, to come into your mind and reveal themsevles to you. It may not come immediately, and it could come to you in some sort of dream state, but I believe you don't need to pay someone to find something that's already within yourself.
Good luck to you in your search.
