Small employers hiring around Milwaukee - what worked for you?

A friend who works at a local manufacturer says there are openings not advertised online. This is my first time dealing with any of this. They prefer people who can start within a couple of weeks. What do you write in a cold email?

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

Keep a list of who you contacted and when. It makes follow-ups easy.
