HELP MY CAREER PLEASE!!!

Please help me with my career. I'm 12 years old and I live in Perth, WA. Here is the thing... I LOVE ACTING. It's my life and without it in my life, I don't know what I would do. I would do absoulutely anything to get any type of job. I'm one of those people who wake up every morning and acting is the only thing I think of. It's what makes me get out of bed every day and what guides my life. I don't care about fame or wealth, I just want to do what I do and love most: Acting. To me, the difference between Hollywood and the local theatre is tiny, as long as I fufill my dream. I have wanted to be in show buisness since I was 6 and have never given up. I don't have alot of experiance, but I am in progress at the moment. I am soon getting professional headshots (they should help...). I am willing to travel nationally across the country and play any role availible. I have already looked at several agencies, but can anyone please suggest a good agent?? People have told me I am a good actor and that it would be a great path for me to take. I have dark tan skin, chocolate brown curly hair and hazel-green eyes that would like to take part in any production!! Please help me acheive my dream, Thank-you so much, Aurora :) .
