Beetle hunt eh? good luck mate...i'm on the same mission. But why '62 OR '72? Big difference between the two. You'll get a half-decent '72 with your eyes shut in Khi...trust me there are loads and loads of late model Beetles waiting to be rescued.
But as for the '62...now that's a little more difficult, but not impossible. There is a very nice and totally ORIGINAL '63 Deluxe in Pindi I saw a week back still in 30% original paint, Beryl green drives great. Owner is a wacko collector, he's looking for around 100k. Even the seat covers are factory (green leatherette).
There is a '59-60 Sunroof Beetle (ragtop) in Saddar Khi but I'm finalizing the deal on that one
