How can I start an acting career, where can I go and who can I go to?

Do your research, especially if you don't find your answers here. Go on google and find out exactly which courses or what experience you need to get into an acting career. After completing that, start researching acting jobs. It's good to start with your education in acting, actually learn how to act well, and gain the necessary experience you need for a career. Consider going to some professional acting classes with a good teacher. After that, you'll have to get yourself out there so try to make as many friends and gain as many contacts as possible while still learning or attending classes.
