Jobs at small Salt Lake City companies nobody posts about - first time posting

Two small Salt Lake City employers told me they are hiring but have not posted yet. One is a print shop, one is an accounting firm and one is a clinic. Does anyone have similar leads?

A short email with two sentences about what you can do and your résumé attached worked for me. I followed up after a week.

Keep everything in writing and save the confirmation numbers. It made the follow-up calls so much easier.
