Everyone is saying "send them into mags"
I would disagree.
I think that she should only send in photos when they are requested, ie photo contests and the like.
After she builds a legitimate portfolio, build a website, and then send that to a company with a message like "here's where I live, if you need any coverage in the area let me know" have her mention she's down to travel too.
Nobody wants a bunch of emails saying "look at my photos! buy them please!" I'm sure they get that a lot. If she has talent and a solid portfolio with a legit amount of shots, showing skill in multiple situations and sorts of skiing photography, then she has a much better chance.
