Hey there!
Just so I understood correctly, you have 15 images which need to have 3 different color edits each, coming to 45 total color edits, is this correct? Could I see all 15 images?
Anyway, I could start working on this right now, just let me know!
I'm well experienced with both Photoshop and Illustrator,
having worked for many years as an art director in ad agencies
You can see samples of my stuff in my profile
Cheers!
