@Ni9ht, you can use the upload pack function to provide a maximum of 50 images in a pack. You are restricting to 6 images at a time for individual images, but you can upload as many packs as you want.

That said, these are quite easy images to cut tbh, so why not try giving them a go yourself instead of depending on others to do them for you. It's really not as hard as you might think to get excellent cuts quickly and for free.

I recommend using remove.bg for your cuts. It's a fantastic free online tool which does the heavy lifting for you by removing the background in the source image, leaving you to only rotate, crop and/or nudge the collar upwards. It's tremendously easy to use and provides fantastic quality. With it, you can go from source to cut in a couple of minutes for the vast majority of images. Take a look at this thread for guidelines for cutters and video tutorials for some more info on what we expect for from our cuts. 

Here's a couple of videos on how to use remove.bg, one when combined with Photoshop and another using photopea.com, which is a free online app so close to Photoshop that it has the same shortcuts, layout and icons 😉 If you don't have Photoshop, photopea.com is the tool I would recommend to use to tweak the draft cut produced by remove.bg. It's more powerful and versatile than GIMP and other similar tools.
