I need backgrounds removed from 100 images. Need a professional that does not cut corners.

I have thousands of hi res photos i need the backgrounds cleaned and made transparent or clear(some of products like purses, jewlery, and some of people). I need to know what you'll charge me per batch of 100. Please make your bid for 100 photos. You will never lower the resolution of any of them and the job must be done with perfection. Any examples of your work would be much appreciated.
