My trip to the states for basketbal

I am 17 yrs old, and just graduated Karratha Senior high school. I travelled to Perth In the school holidays for a basketball trial. I was successfully 1 of 27 chosen students from Australia for the AUSA hoops to travel to America in April 2018.
I have a chance of a life time to show case my talents and compete for a US college scholarship. This is a 21 day tour where I will be up against some of the top high school players in America. I have a huge passion for basketball, this is a huge opportunity. Please help support me and make this happen. Every dollar counts:) At the moment I only have a job working school holidays as a programs assistant at the local lesuire Plex. Any help will be much appreciated.. :)
