Word-of-mouth leads in Buffalo

A friend who works at a local manufacturer says there are openings not advertised online. There are 7 people counting on me, so I am trying to be careful. They like a brief email with a résumé. Does anyone have similar leads?

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

Visiting in person worked for a trades job. For office jobs, email was better.
