Angel's Football trip to Australia

My son Angel was selected as an ALL STATE football player and was invited to represent the State of California in a 9 day tournament in Australia. This trip will cost right about $5000 but will be an experience of a Lifetime for him! The cost of the trip includes roundtrip airfare to Australia, hotel for duration of trip, travel to and from tournaments, tournament entry fee, uniforms, 2 meals a day and sight seeing adventures while there. Angel played Varsity QB at Garden Grove HS for 3 years and made so many accomplishments, including taking his team to 2 CIF Championship games. He is very dedicated and has a heart for Football and his Family! He comes from a home with 3 younger brothers and a single mom with one income. As you can imagine, finances are tough. Any help would be GREATLY APPRECIATED!
