Cut out images

I will need 87 products cut out from the background with a layer mask in Photoshop. The products have already been shot in a light tent on white background, so there shouldn't be major issues with separation of colors. There are a few complicated objects that have some wires and other small bits, but most of them are medium to simple edges. I attached examples of simple, medium and complex objects. I will need the images to preserve a slight shade in front of them so that they appear to be standing on the white surface, not floating in air. I have attached a PSD example of how the final file should look. You can make small contrast, clarity adjustments as you see fit, just don't go crazy (I don't want to see 255 highlights or 000 shadows on the objects - if you don't understand what this means, please don't bid). If you make contrast adjustments in Photoshop, please use adjustment layer. If you use brush/contrast adjustments in Lightroom, I will need the catalog file. I will send you a download link with RAW (CR2) files, and I will need layered TIFF files back. You will need good internet connection, as the files are quite large. I am a pro photographer and if the project goes well, I will have plenty of work to give in the future. :)
