Changing product photo

A photo shoot for the product of a future e-commerce has been achieved. All products have been photographed on a green background. You have to remove the background of each product and resize them to around 500 pixels (depending on the direction of the photo) You must ensure that all products are right and center in the psd file you send me. You will need to edit any photos of the product to ensure there goes any imperfection on the product. If there are imperfections, you will need to edit. The file contains 171 phoros to change. You will need to send all picture change in PSD. We add a photo attached as an example.
