Crop Images Picked from a Website

You will be asked to pick at max. 6 images from around 16 images for each product, crop the images to get rid of unwanted parts and then save to files. There will be rules about how to pick, crop and save the images. I will give more details later. I am looking for the right freelancer to work for me in a long-term based, so for testing purpose I will only give the winning bidder 600 products for this project. If everything goes well, he/she will be repeatedly invited to work for the same kind of project. Thank you!
