Help me attract more clients and followers through Social Media & Digital Marketing

I have a sub brokership firm in Mumbai where we provide our clients with means to invest in equity, mutual funds, IPO's etc. With the growing awareness in today's youth about the benefits of trading and investing in stock market and creating wealth for their future, I want to tap into it and increase my clients and have a good amount of followers to earn from social media posts as well. The stock market is such a vast thing that we will never run out of content. My ultimate aim is to attract high net worth individuals and create a good clientele and offer them portfolio management services as well.
