Need a starter motor and my radio doesnt work
 

Hi guys I’m completely clueless about cars ....

I own a Chevrolet Aveo 2009 model and it’s having a few issues.
I was just wondering if any of you guys could help me?

1- I need a new starter motor but have no idea what one it is I need and I don’t want to be spending my life savings on one

2- my radio and interior light don’t work, I’ve checked the fuses and they seem fine

TIA x
