IPhone 8 Plus

Hello guys, well i think i'm facing same issue that happened to lot of people.
After a small phone drop the back camera turned to black and no longer works yeah i tried the settings and reset part and the software update and such but it's technical i means seems like something is wrong inside the phone so i wonder if anyone did repair such thing before ? how much will it cost ? and is it risky specially that the back glass is a bit broken.
Note : I'll not stick with it i want to repair and sell it i no longer like this IPhone 8 Plus
