Help me to get to Chile.. Poor student in need

I am currently studying animal behaviour & welfare. As part of my third year module we have a optional field trip to Chile where we will carry out research in the Atacama desert. I have managed to book my flights already but I still need to get a passport, book travel to and from the airport, a internal flight and funds for a hostel whislt out there. I am hoping to manage to raise the funds otherwise I will have to cancel the other flight and loose my money. I have now finished for the summer and I have endlessly been applying for jobs to help fund this trip. No success as of yet and my time is running out.
