How do I handle the second paragraph of my cover letter if I am not responding to an advertisement for a specific job? (The podcasts seem to focus only on replying to jobs posted on and other job boards.) My specific situation is described in the next paragraph.

I am recently unemployed, and am having difficulty finding a new job in my field (I have worked in healthcare as a technologist for 4 years). At this point, changing careers is preferable to moving out of state due to family concerns. I met a pharmaceutical sales rep who is willing to meet with me and forward my resume to her district manager. There is no posted opening, but she seems to think she can help me find an opportunity with her company.
