I need photos photoshopped on white background and some editing

We need to remove background from lifestyle photos to make it a photo with dress only like here: https://www.wolfandbadger.com/uk/category/women/clothing/dresses/?p=2. Needs to be photoshoped so that there is no hair, hands (or any other human parts) on the dresses, some dresses need to be photoshoped to full length dress where there are pulled up skirts such as in the attached example and to make photos with hands down where hands go to sides like on the example. Please photoshop 2 photos attached to demonstrate understanding and skill.

We will need to do 55 dresses in total, all are similar to the attached. Need fastest delivery.
