Help send kids on Malaysia karate tour

My two sons have been selected to represent South Africa at tournaments and training camps to be held in Malaysia, Singapore and Thailand from 20 December 2018 to 5 January 2019. This is a dream come true for my kids as they have never been out of the country. They have been in the sport for a few months and have shown great improvement and enthusiasm. Each student is expected to raise their own funds. The total cost per child for tickets, accommodation, internal transport and kit amounts to 25000 South African rands. All donations and sponsorships will be greatly appreciated.
