Word-of-mouth leads in Birmingham - 6 months and counting

A friend who works at a local manufacturer says there are openings not advertised online. I do not usually post, so bear with me. They prefer people who can start within a couple of weeks. What do you write in a cold email?

Thanks for writing this out. I went through something close to it last year, and it got easier once I kept a simple log of every call and form.
