I have also received the application form and began to smell a rat.
There is another
Impex Engineering, based in Malaysia and I've emailed them to see if the two companies are linked in any way (they
appear to be genuine).
I guess the first thing you have to realise is that if it's Nigeria there's always a chance of a scam.
Impex Engineering Ltd (suspect) even has a
scam warning on its website (good spot on the free google site issue Brownlees).
Has anyone out there advertised with Flight Global? What checks and controls do they have for advertisers? Does it cost anything?
