@shahrukhraza we do not know what is available in Saudi Arabia but you can do this repair yourself. Since iFixit does not yet have a guide for this, You can use [https://www.youtube.com/watch?v=BsOx_W8JN6Q|this video] even so it is a slightly different, it will show you how to remove your display as well.

The assembly is available at many online sellers. I am not sure about delivery to Saudi Arabia etc. That is something you will have to determine.
