According to his signature, he has 4 GTG's. Feel free to contact those members ... also, in his profile, it says he is a teacher. Means nothing (I guess), but I could trust him. Get ALL his information and have a phone conversation with him. If you still have a few doubts, feel free to use a middleman ... I can offer this to you if it gets the deal done as long as I have no money out of pocket.
Hope this helps !!
