I MAY ALSO BE DEALING WITH A SCAM...

I was sent an email by Dr. Shing Han who gave me an address in England. He asked me to send my teaching certificate which I directed him to a web site where he could check it himself (it is public). I sent a resume and within days he offered me a job and had his attorney Sir David Normington, send me a contract. I signed the contract after asking about the 800 GBP's that he would require I send via western union. I asked if I could simply show that I had funds in my own account here. He said that they did not accept bank statements and I would send the money to myself from a friend.
IS THIS A SCAM?
