Jewelry Image editing

Hello I am looking for someone to edit a few images for a website

The images are pictures of jewelry ( rings,necklaces,earrings

My offer is 13$ USD for 40 small pictures

I would like to have the images so that they are cut out have a white professional background and possible have images cleaned up and cropped so the images are in the center

- Cut out with white background
- Retouching
- Cropping so image is centered
- Ensure the colour temperature accurately displays the metal Colour

Attached are examples of what the pictures currently look like

If possible I would like to have these images done as soon as possible

Thank You in Advance
