Going to the world debut championship in Mexico

Hello, world! I'm Tamara and I come from Serbia, a small country in the Balkans with a very low standard of living. I have been very successful in debating and I won various domestic and international tournaments. The next step is, with a little luck, to win the World Cup. But that path is very expensive for our standards. The average salary here is 300 euros, and I live in a five-member family. Participation in the tournament costs 500 euros, 1660 euro plane tickets, plus the accommodation that I have to provide myself. All people who want to help are welcome. Thank you!
