The entertainment industry is vast. First, do you live in Los Angeles? If not, you'd have to relocate first. If you want to just work in a clerical field, there are a few agencies that place at studios and production companies and there sites at USC and UCLA and especially at AFI (American Film Institute) and there websites like hcdonline.com and the trade papers...studios used to have their own 'temp pools' and these days, you have to be creative-start with an intern position first...MINGLE and NETWORK anywhere you can and advertise your own skills when you get here- to LA, I mean
