Buying my own media documentary equipment to cover

I'm a self-proclaimed journalist and I want to do a documentary. However, I don't have enough money to buy my own equipment. Documentary is an expensive profession but I want to make my own low-budget documentaries and they will be uploaded on my YouTube channel. Most of the documentaries will be about poor people in the country. This could also be my way to help them by exposing them and finding sponsors for them.
