how does the PR gain from the media

I’m a public relations major but I’m really unsure of what I could do with a bachelors in this field. I love fashion but I also wouldn’t mind working in the medical field. Any careers in public relations where I could work in either field would be awesome!

I am looking for the shortest possible time and least expensive way to achieve this goal.

I keep finding these “too good to be true” small marketing companies that do nothing but sales and are commission based. I’m looking for marketing communications and research in chicago.
