I need a high end jewelry photograhing editor

Hi
We require a jewellery retoucher for long term business.
Currently we have a jewellery retoucher but he is closing his service soon.
We want to follow the same style of editing.
I have included before and after photo for your reference.

We require clipping path, colorstone changes on some jewellery, gold color changes ( 3 to 5 color change), stone enhancement, cleaning of dust and redrawing jewellery shank, color correction of photo and more.

At the moment we need about 100 photos edited, then more will follow in the next month.

Each photo we need:
FILE IN TIFF with layer
Stone change on some image
Gold change on all image (3 color change)
Clipping path of Gold
Clipping path of Gemstone
Clipping path of Diamond
jewelry shadow

I have uploaded a before shot (in white gold with a london blue topaz) and an after shot (in yellow gold in garnet) - this was edited and this quality is what we require.

Thank you.
