Small employers hiring around Toledo - what worked for you?

A friend who works at a local manufacturer says there are openings not advertised online. They like a brief email with a résumé. Should I visit in person?

Visiting in person worked for a trades job. For office jobs, email was better.

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