Word-of-mouth leads in Sacramento - 12 months and counting

Two small Sacramento employers told me they are hiring but have not posted yet. They like a brief email with a résumé. 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 12 months ago, and it got easier once I kept a simple log of every call and form.
