As a full pay at LACs, i think you are underestimating her chances of acceptance. She has a nice strong verbal score, a strong interest in a major that many students, with future earnings in mind, are moving away from. Clearly, she is not a math and hard science student, but that is okay, considering her stated interests.
Shoot higher! She will probably get accepted everywhere you mentioned (except maybe Skidmore), and possibly at more selective LACs too. Not Williams and Amherst, but definitely has a a shot at the next tier down. I do not care how much LACs claim they are need blind. They need money, and they need English majors. She is both, with a record of publications already. Say openly no need for fin aid by not applying for it, and English/writing major, and doors will open for her.
