Help me get a new PC

My name is Joseph and I'm 15 years old. I live in LA (Don't worry I'm good) and I want to start streaming on twitch but I don't have a lot of money right now and a good PC is really expensive. My parents want me to earn money but there isn't a lot of jobs that are hiring my age right now and it's really hard to earn money only as a kid. The picture is my friend's PC that I'd get something similar to. I'm grateful for all donations and thank you so much for your help.
