If you want to send me 3btc to work on this a couple of more days and put together a report then do it. If you think that is high, to bad. That is about a rough after tax rate including hotel and food that I could make doing it otherwise. If you want me to teach you how I research I usually charge a student the first month of their pay so ~15-22btc, but I rarely take on a student.
If you want to continue to doubt the authenticity of the document then find an escrow and put up some btc.
