Just need to edit the color of logo on shirt

I'm looking for a freelancer to help me edit the color of my logo on a shirt. Currently it is other color, and I'd like it changed to black, specifically a jet black shade. The current color needs to be identified before changing and I specify that I want a jet black shade. I'm looking for a freelancer who can help me out with this project so the logo can be edited to the right color. Thanks!
