Good Graduate Film School in Canada, USA but do not have a BFA but a BA?

Want a graduate school where I can do Film Production mostly but Film Studies is o.k. Do not have a BFA in cinema but a BA in Sociology. Took courses in Cinema, Film Studies, did short films, wrote scripts. Need a place when I am finished, I can work as a filmmaker or screenwriter without problems. Where I can get well-rounded knowledge of cinema, the industry and technical skills. What do you know about fellowships, scholarships, boursaries and general GRE? What does my general GRE score need to be? What should I write in my letter of intent? With BA do I have good chances to enter? The truth about my GPA requirements (be gentle) ? Should I write a script or just give an essay in Sociology or Film Studies as a writing sample? Careers opportunity? Truly they cannot be that bad? Average annual salary? Filmmakers-- BEST thing about job? WORST thing? If you been to graduate Film School, please give, tell your experience of applying and going to school.
