Sole prop vs partnership vs llc

Hi

I teach Technical Analysis to my students through videos and offer stock market training service. My yearly income through teaching is in a range of 15 Lacs at this moment. I am a one man shop.

Should I operate as a sole prop or should I start operating as partnership concern or a partnership LLC. What are the legal and tax pros and cons. Kindly share your suggestion so that I can make myself more efficent from tax and legal standpoint.

Regards,
