Photoshop. Blur some areas on some images and more

READ BRIEF ALL THE WAY TO THE END, AND WRITE A PROPOSAL THAT MAKE SENSE. NOT A COPY PASTE PROPOSAL. I have a project with 72 3D rendered images of a building - taken 360 degrees around the building. I need the same "gorund area" in each image - not the same area on each file. Because as the angle on each image changes - as it turns around the building, the area that is to be blured are the same - but it will change position within the image. Have a look at the attached files and you will understand. After all images are blured, we will put a compass icon above that area - that are predesigned - to show the direction of north and south. I have attached a few images, 5 in total that shows how it turns around. And I have attached one image that shows what area that should be blured. Before I choose a Freelancer, I will need you to do at least 3-5 of the images in the dropbox blurred. So I am sure you understand how to blur it- and how it changes area as the image changes angle from image to image. I do not have time to keep explain this individually to freelancer, so if you dont understand what need to be done, please dont waste my time. Read this ´brief properly and look at the files before you send me a proposal. It is 72 images in total, and we have different edits to do. So I expect it to be 3 - 5 hours of work if you work efficient and are good. PS! Very important is that you save the files without any loss in quality, I need the same quality images after edits.
