Mannequin cut outs and image background changes

Hello,
I need an image editor who works with editing flatlays/manniquin retouching work.
I have 2 mannequin shots to be cut out but the shirt one needs the neck labels/design reproing into where the mannequin neck has been removed.

Then I have 1 image of a model and dog on a scoop that needs cutting out, adding a drop shadow/natural shadows back and amending the background colour to #f1f1f1.

Finally 9 images of sheepskin slippers need cutting out around the shearling fur and adding a drop/natural shadow with the background colour being #f1f1f1.

Overall 12 images in total.
