Repair fix method or cost of replacing an iPhone 11 screen and camera

So I recently threw my PS4 controller down and it smashed my front screen of my iPhone 11. The screen is still useable and it has minor display damage with some orange bleeding in some areas. The real damage hit when I figured my rear cameras and flash are not working with the flashlight not turning on and the rear camera’s not working in any app.

Does anybody know if the camera issue could POSSIBLY be software or if it is definitely hardware-based?

Would it be easy and cheap for me to repair the screen and cameras myself or would it be better to take it to Apple/third party company to repair it?
