I used Jack at Firstdream to have one of his associates hand deliver flowers and confirm that one lady was real.
They had a picture of her that I sent via e-mail to them to verify her identify. They had her write a short note to me when they delivered the flowers. They scanned that letter and a photo of hers e-mailed this all to me for a very reasonable price even though they had to go to her house more than once to get contact..
I did this because of the fact that she said she did not have a phone and we could only use the service for such calling her there.
