Hi, I'm just reading up on some similar offers and from what I can see I'd be careful of "Ken Stuart". He (or someone else) posted exactly the same response about Edcomasia in 2006 which suggests that this offer was received four years ago (which would be 2002 at the time of posting) under the username Khun And. Unless he has since then suffered from some severe memory loss or indeed has made some startling discoveries in the field of time travel I would suggest that this is a fake (as 4 years ago from the current post would be 2008, a good 6 years after the supposed original job)

There is of course a possibility that this is entirely unjustified and is a mere oversight from dear old Ken, but just to draw attention to these apparent inconsistencies.
