Small employers hiring around Honolulu - 11 months and counting

Two small Honolulu employers told me they are hiring but have not posted yet. I have read a lot of threads here and could not find my exact situation. One is a print shop, one is an accounting firm and one is a clinic. Should I visit in person?

Thanks for writing this out. I went through something close to it last year, and it got easier once I kept a simple log of every call and form.
