Processing RAW photoshoot to combined publishable product photos

We are a small marketplace agency and have image enhancement and editing jobs with some regularity. The job to be done now involves a product shoot of socks.

Process approximately 35-40 RAW images of socks and merge them into images that can be used on Amazon. Some of the tasks involved include:
-adjusting exposure
-adjusting colour so that the colours of the socks match the colours of the same socks on the customer's webshop
-make the socks free-standing
-adding and/or manipulating different colour dots
-merge into images with 5 and 7 socks with shadows that match the customer's existing images in terms of placement, perspective, etc. (see example)
-generate PSD files with paths etc., Tiffs and publishable PNG files

See examples.

N.B. We need high quality. So we need you to have experience and need to see examples you did on similar jobs.
