Best Places to Find a Job for Someone Who is 60+

I live in Missouri, but I am helping my mom that lives in the Homestead area and needs a job desperately. She is 63F and has 2 decades of supermarket retail experience. She got let go at her last employer after 14 years where she was a front end supervisor. She got a part-time job with Publix where she is only getting 11 hours a week. I am helping her constantly to apply for jobs and fix her resume. I looked on Indeed and Snag a Job and there is hardly anything for her. Most jobs are plastic surgery sales and part-time retail paying $14 an hour. Is the job market in Miami that bad? Her English is not very fluid, but knows enough English technicality for her position. Every time I go to Miami, the store and restaurants employees don't even understand hello so I don't think it should be a big problem. These Miami salaries are unsustainable for the cost of living, I don't know how people do it. Even in St. Louis the pay is a little higher, but our rent prices are half. Before you mention about my mom moving to St. Louis, she has my siblings and nephew and refuses to leave them.

Any suggestions where she can apply for employment?

Thank you 😊
