Product Photography Edits

We are in the process of launching a new company site and are updating our image library with new product photos to populate the online product catalogue. Photography is been taken care of internally but we need to outsource the editing component to speed up the process. This will involve, receiving a shared folder of raw images that will need to be edited for: Size (1600x1600pixels), Deepetched, and edited to enhance the image in some instances by adjusting gamma or saturation levels ( for instance in products like casters). Images to be saved in source folder as PSD format, and then in their respective product category folder as a jpg file. Photography includes products in the following categories: Castors, Wheels, Hardware, Hooks, Felt and floor protection, Dollies, to name a few. I have uploaded some images of the products to give you an idea of the products and final results needed. We have over 1000 images being shot with the potential for more, so we would like to receive the pricing per product edited or if an hourly based on products completed/ hour estimate.
