Hi rrhood,
I think you should include them, not only because you are struggling for numbers, yet also from an ethical point of view: you have interviewed them, "no news is news as well" etc.
I agree that having to transcribe those interviews is a bít of a pain, as it will not provide that much interesting stuff. Evenso, when you publish your research it will strengthen your argument and you do not have to find excuses for why certain people have been excluded.
