Jobs at small Minneapolis companies nobody posts about after 16 years as a warehouse supervisor

Two small Minneapolis 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?

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.

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