"The big time" is an informal noun meaning the highest or most successful level in a career, and it's usually used to mean Hollywood (the film industry). This is what the speaker is referring to here. Ex: She didn't want to play small shows anymore. She was ready for the big time. Ex: The singer shot to the top of the charts as soon as she debuted. It didn't take long for her to make the big time.
