Help a student purchase Cheryl Porter’s Vocal Courses

My dream is to become a vocal coach in the future. I need some practice to get into university and I really want to purchase Cheryl Porter's Vocal Courses to help me. I also plan to take other courses in the future. I am currently taking vocal classes, but they cost a lot. I lost my job, because of a pandemic. I also study English literature, so I only have money from the scholarship. It barely covers the price of vocal lessons, that's why I cannot purchase any courses.
