Damn you Alex!! I hadnt thought of that one LOL!
Maybe if I wrote the letter for them in advance, they could then just sign it, and I could print it off on one of their headed letter sheets. A big X would do, which is quite apt considering the number of big X's being written today!!
Thinking laterally here, would there be any reason why I couldn't use a letter heading of one of my companies? And get one of the other partners to sign it? Theres a guy on a VW forum who does Subaru conversions, he's offering his services to anyone who sends him a couple of pics and the engine details, and he'll put together the letter
