Blind mother needs help buying family car :)

Our story: Hi I’m Katie . I’m legally blind, mother of two on permanent SSI. My daughter Makela will be 19 in October and my son David will be 15 this month. I need help buying them a car to share.. Makela graduated high school this year with a scholarship to Great Plains Culinary Institute at Southeast and has had a full time job for almost a year. My son David is starting his freshman year of high school in AP classes and is saving to take a drivers Ed course. Any help to get a reliable vehicle would be such a leg up for all three of us, a big quality of life change for my family.
