Anyone working in Aligner please let me know how to start and how much money can I make

I am looking forward to replace my freelancing business with Aligner work. In freelancing currently I have 2-3 clients on and off. I make minimum of 2 lacs+ per month. I am looking forward to something where I can earn more than that while taking less stress. I am ready to grind for that. Please suggest! Will be grateful always 🙏
