35 image cut out for white background + 2nd cut out of a part of product

35 images must be cut out in 3 steps. A guy is wearing differnt clothing (jackets and jeans) -in first step the complete guy must be cut out for a white background -in 2nd step the body part, of for example a leather jacket, must be cut out (seperated from the guy). SO at the end the main part of the jacket stays -in 3rd step all applications like zipper, buttons.. etc. must be cut, so that the only the leather body of the jacket stay 100% alone, so that its possible to change the color of the jacket to other colors. please see the attached image with descirption, for better understanding
