Volunteer tutor needed: English writing for a motivated student in Bangkok

My son, Prasert, is 11 and in the final year of school. Prasert loves school but English writing has been a struggle since the school was closed during the floods. The school-leaving exam is in July. We can't afford a private tutor, and the school's free sessions are full. We're looking for a volunteer who could spend an hour or two a week, in person in Bangkok or online, for about ten weeks. Prasert 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 English writing, you could change the course of Prasert's year. I never thought I'd be the one asking, and I'm grateful for every bit of support.
