Jobs at small Madison companies nobody posts about - what worked for you?

I asked around at a community meeting and got three leads. This is my first time dealing with any of this. 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 9 months ago, and it settled down once I kept a simple log of every call and form.
