I've got a lot of editorial concert shots, and obviously they are all noisy (during a concert it's frequent to shot at 800iso or even 1600iso).
I've got also a lot of "low-light-noisy-shots" (it seems a light film grain, not too much disturbing)

where can i upload and sell that shots?

Try FeaturePics, put a note to the reviewer in and explain the situation. They accept editorial and you can even set your own price. SY

I don2t know if grp_photo was kidding but  I remember reading at SS forum  that SS has different quality standards for editorial images so you might indeed try to upload them there
