I need money to feed my gacha addiction

I want to start a YouTube series for the game Raskura (Last Cloudia) where I use only one character to clear all the content the game has to offer. The specific character has an exclusive weapon you can get only be spending a certain amount of money and I want the series to be as realistic as possible. I volunteer in many places but the key word is volunteer. I am only 17 and still in school so I can't get a proper job right now. That's where you come in!
