I need a photo editor (clipping path) 2

I have lots of stock photos of vintage clothing for my business that need editing. Can you please remove the image backgrounds around the clothing and the chain and crop the images to a square 1:1. There should be just over two links of the chain visible (2 and a bit links visible) (the piece of clothing is hung from a chain) . The piece of clothing should be central in the square horizontally. Then I need a shadow applied with 30px opacity and 30px offset with opacity of 55% and angle of 180 degrees. I've attached two images. Image 1088 (2) is an example of the final product and img_3227 is an example of the raw image. Please note what the distance of the clothing should be from the bottom of the square. There are a small amount of images that don't arent hung from chain and just need the clothing cut out and the shadow applied in the same way the shape of the image does not need to be square or altered at all (the image IMG_3218 is an example of this type of image). The exported image should be in .png format and less than 25mb. Thank you! There are 500 images and my price in total to do the task is 100£.
