Bulk images cut out with drop shadow added

We are a very busy product photography studio in the UK. we are launching a new budget pack shot service and are looking to outsource the clipping, crop and slight editing. due to the volume of images we will be producing this would be best suited to someone with a studio or team of editors rather than a part time editor.

we require
images cropped to size
images cut out with precision
drop shadow added

we will be producing between 100-200 images per day - mainly jewellery.
