Perfect Product Images

I have approx 170 product photographs to make perfect for website www.alexisamor.com - all virtually the same with the same requirements. All are sunglasses or spectacles and need to be kept in their current format but with the following consistencies:

Perfectly white background.
Very, very slight shadowing where the frame parts meet the white surface - see website.
Sunglass lenses must be without any reflections.
Sunglass lenses must all be darkened slightly - probably 15/20%
Pics are currently NEF but need to be Jpegs in as high a resolution as possible.
We'll need to do a few trials just to make sure that the work is correct. - Hope that is OK.

Will deliver in two 85ish image packs.
