Get Tim to the world championships

Timothy is 17 years old and still attending school.  He has recently competed in the South African mixed martial arts championships and received second place in continuous fighting, first place in ju-jitsu and first place in mixed martial arts.  Tim has only been competing in this sport for 10 months and has shown complete and total dedication to his training.  He is now able to compete in the world championships in America next year.  We are a single parent family, but feel that Timothy has achieved so much over the past 10 months that he must be able to compete at the worlds.  As we are a single parent family, money is extremely tight and any funding will assist in getting Tim to America.  There are many expenses such as passport, visa's, flights, accommodation, food and kit which urgently need to be covered.  Any help will be very much appreciated.
