Jobs at small Cincinnati companies nobody posts about (Cincinnati)

Two small Cincinnati employers told me they are hiring but have not posted yet. I would rather hear the honest version than the polite one. One is a print shop, one is an accounting firm and one is a clinic. What do you write in a cold email?

Thanks for writing this out. I went through something close to it 5 months ago, and it settled down once I kept a simple log of every call and form.
