I think with something like Icelandic, your best bet is to find a teacher, be it online or in person.

Because Icelandic has a small population of speakers, and less of a global reach compared to languages like French, Mandarin, or English, there will be less easily available resources. It will also be very distinct. I don't believe Icelandic is a part of common language families, like a romance language, or a germanic language.
