Hi I don't wanna bring your hopes down but there is literally no way to make it big in singing. In another words, its more likely you'll get hit by a satellite than become a famous singer. The chances are slim to none. About 1 person every 3 years makes it in singing. Imagine 500 million people who want the same you're doing. How do I know this? Well my family is into Broadway and I have met and known so many failed musicians and its really heartbreaking to have to hear their stories about wasting money and decades to chase something that would never happen. But famous singers today, just get lucky. They are at the right time and place. But don't give your hopes up. Post some youtube and take risks. Good luck.
