Looking for some help with small & large cover!

Hi, I’ve just started writing my first story and I’m not talented at all so I was wondering if anyone could lend a hand and help me.
I decided to write my story in limelight and is called ‘sweet but psycho’. It is about a girl that lives with her mother and younger brother and has to provide for them after her father left. She keeps her job a secret and whilst working she discovers more about herself and finds a new love that’s been in front of her the whole time.
If anyone thinks they can create something that would be amazing, thank you!
