Thanks for confirming this to be a scam.
My wife found it and suggested it, but advised me to check it out, nevertheless. So glad that I did
Personally, got suspicious because of request for money up front and the letter offering the job included "We are pleased to inform you that we are in a position to utilise your services in the areas that you specified," yet none was specified. This made we suspect that it was a standard letter and therefore possibly a scam. Also there is no talk of a contract for you to be working with a supposedly reputable company.
Definitely not to be taken seriously. My advice: stay clear.
