Small employers hiring around San Diego - 23 weeks in

A friend who works at a local manufacturer says there are openings not advertised online. Any experience at all would help. They prefer people who can start within a couple of weeks. 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.

Small employers often hire on recommendation. Ask neighbours, former co-workers and your library.
