My favorite Indian stock market is Moneycontrol. It is quite user friendly and informative.

I think you should also add Finvasia in your list.
The broker is giving tough competition to all discount brokers with its unbeatable pricing model. They have zero brokerage across all the segments.Trading platform is highly stable and doesn’t hang or freezes every second day like zerodha. Customer support team is highly responsive.

I would say taking loan for the investment could be your one of the biggest mistakes.
