Image editing - repost

Hi, we have about 1400 images that need editing i.e. increasing or decreasing the size of the image and then do some cropping to achieve a set ratio of px which we will provide and we have about 870 images already on white background that need to be edited to have a white background as big as the set ratio of px which we will provide attached are the examples an original image on white background and the same image which we have edited to fit our required px measurements on white background an original image on mood (not white... could be anything, could even be set in a room...) background and the same image which we have edited to fit our required px measurements on the original mood background What I need from you is: How many days/hours will you need to work on this project? How much do you charge per hour? Thanks
