Remove green color from skin in 30 photos in Photoshop

I took some photos of a guy who was standing in front of a green screen, but unfortunately he stood a little too close to it and some of the green-ish hue splashed onto his bald head. I went ahead and got rid of the green background, so what you have here are photos with a transparent background, but I need the green around the head removed as much as possible so that it blends better with the surrounding skin. Attached to this project is one PSD file to sample. I have 29 more to do for a total of 30 photos. I would appreciate if you could show me how well you can do it and then I'll hire you and we can get started on the remaining photos. I don't suspect this will take very long to do once the right blend to the skin is figured out, so I am hoping this is a low priced project. If I am mistaken, please let me know. Thank you for your time.
