opinions please

just wondering what people think of the casting call notice on the site Dare2audition.com.au regarding an up coming feature starring steve martin and maerryl streep. I would love to be a part of this site and see what happens regardless but I can't afford a one off payment of that much. I'm already paying off my personal loan for the part time training i'm doing... Is it worth signing up. I have a proffessional hadshot.... i just dont like it....a bit bold and the beautiful..... grrrrr the likes of being a poor dancer singer actor :(
