Jobs at small St. Louis companies nobody posts about

I asked around at a community meeting and got three leads. One is a print shop, one is an accounting firm and one is a clinic. Should I visit in person?

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

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.
