Patent an Innovation

Hello all, i have invented a device for society. Before i disclose it publicly, i need to patent it. But when i reached the sources they told it will cost around 50K INR. I struck in the middle. Neither i can tell my parents i did this ( who thinks i am always useless person) nor i can start a business 😔. Dont know what to do #patent #innovation #startupfounder #idea #invention
