Photoshop background on 51 photos of appliances

I have 52 photographs of appliances that need background changed to something more appealing, for display in web marketing. In addition to changing background, appliances should be rotated as appropriate so they are square. 4 photos have been attached providing an example of what needs to be done. All photos can be provided on request but cannot be uploaded here as is 50MB total. Job requires that photos are returned as: *Photoshop psd files, and jpg files with no logo watermark overlay, and jpg files with watermark overlay. Watermark fil;e provided * 72 dpi, 3000 X 3000 pixel RGB, unless that will result in image degradation. In some cases images will need to be 2000 X 2000 pixels. File names to carry identifier of size, ie 2000, 2500, 3000. *All jpg psd and watermark jpgs must be renamed with folder name they are in, numbered as necessary so file names are not duplicated. * Whether jpg image has overlay should be denoted in file name as O (overlay), or NO (no overlay) *New file structure: FOLDER NAME_O/NO_RESOLUTION_NUMBER. Each folder to have a minimum of one psd file ie. Please do not combine all images of all folders into one enormous psd. * PSD layering must be labelled, and separated into wall, floor, appliance(s), watermark. *Background image must be open source or original work and look realistic *All appliances should be centred in middle of frame, with appropriate ‘white space’ around them. This is particularly important for files in the folder ‘fridges’, as these files will later be mirrored. Only quotes that include one JPG edited copy of one of the attached sample images will be considered. Please message me with the edited copy, so I can find it easily and shortlist you :)
