African Wildlife Rehabilitation

Hi everyone,  I am a college student who is very passionate about the environment and specifically wildlife. In July of 2015 I plan to go to South Africa and volunteer my time at a rehabilitation center for injured and endagered animals near the city of Johannesburg. I will be working with Cheetahs, lions, giraffes, elephants, and all other kinds of animals, taking care of them, building them new enclosures to live and just simply nuturing them. I need your help to make this happen because I am only a college student.  Thank you so much for taking you time to read this.
