Dear Sir,
I noticed an ad. In the paper today you said you were looking for people to join your expedition 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 experience of traveling the hard way which should come in handy on the expedition 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
