Dear Sir,
I noticed an ad. In the paper today you said you were looking for people to join your e_pedition team. It sounded as if it might be fun so I'm writing to say I'd like to come along.
About myself: I left school at 16 because I wanted to earn a bit of money. After that I got a few part-time jobs as a waiter, etc. But I didn't stick to any of them for long. Recently I've been doing a bit of hitch-hiking round Europe so I've had some e_perience of traveling the hard way which should come in handy on the e_pedition you're planning. By the way, I'm a great guitarist so I can keep you all amused round the campfire at night.
Let me know when I can call in for a chat about dates and other details, etc.
Yours,
David Smith
