Documentary filmmaker needs a movie poster for a film that will screen in an upcoming festival

This is what a business in United States was looking for in their poster design

I am a documentary filmmaker who has recently had a film accepted to screen in a film festival. The film is called "A Quiet Strength" and the film synopsis is:

A single, working mother in the heart of the Mississippi Delta sees hard work, education and faith as the foundation for raising her three high school daughters. She is neither a hero nor a victim of society, but rather a simple, hardworking woman who puts one foot in front of the other each day with quiet strength.

I have some photo stills that I took from the film. I am looking for a movie poster that communicates the idea of "quiet strength". I also want to it to somehow communicate the setting - deep south, small town, lower socio-economic group while respecting the main character as neither a victim or a hero. But a solid, dependable, humble woman.

I can provide a link to view the 18 min documentary to get a better sense of the film. Read more
