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

My nephew, Shawn, is 14 and in the final year of school. Shawn loves school but computer science has been a struggle since the school was closed during the floods. The GCSE exam is in November. 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 Shreveport or online, for about sixteen weeks. Shawn 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 Shawn's year. I never thought I'd be the one asking, and I'm grateful for every bit of support.
