What are my chances of getting into USC?

I am a Junior in high school. I have all A's right now except for in Greek and Rhetoric. I have a C in greek, and a high B in Rhetoric. I really want to get into USC to major in film scoring. I have been a part of several different locally known bands, in which I have played guitar, banjo and piano. I sing and write and am currently working to get an Album out under the aid of a World famous christian artist. I have played at dozens of events through the years, including working as the pianist for an upscale steakhouse for a year, and am currently playing at different restaurants with guitar and voice. I have been home schooled 9th-10th grade and am now in a private organization called "Veritas." All I want is to get into USC, I can figure out how to supply the money. What do I need to do and what are my chances of acceptance?
