Volunteer tutor needed: computer science for a motivated student in Bloemfontein

My son, Jacques, is 13 and in the final year of school. Jacques loves school but computer science has been a struggle since the school was closed during the floods. The GCSE exam is in December. We can't afford a private tutor, and the school's free sessions are full. We're looking for a volunteer who could spend one or two hours a week, in person in Bloemfontein or online, for about twenty weeks. Jacques is polite, hardworking and eager. We have a quiet space and a laptop for online sessions. I'll always be at home for in-person sessions. If you're a teacher, student or professional who feels comfortable in computer science, you could change the course of Jacques's year. Please ask me anything in the questions section. I'll answer honestly and quickly.
