International HOSA Competition

I am part of an organization called HOSA that is dedicated to teaching students about the health and medical field. I competed in a Mental Health competition and was honoured to receive first in the state. This qualifies me to go to the international competition that is hosted in Dallas, Texas this June. The competitors have to cover the majority of the expenses which include hotel stays, registration fees, and the travel costs from Wisconsin to Dallas, TX.  Any help would be greatly appreciated.
