Trek's get flamed here a lot it seems. BUT, Trek makes up to a 64cm frame on some models. Here's one with an alum frame and carbon seat stays/fork (although I don't like the wheelset for heavier riders it would probably be fine for starters.)

I'm a normally proportioned male 6' 6" and the 61cm Trek frame fits me fine.
If your friend wants a more upright position, just change the bars and stem.
