Do you have Photoshop? If so, I can give you some advice on how to color it in yourself.
When coloring in on Photoshop, I usually use two to three layers. One for Skin and clothes, one for hair, and the other for eyes and shading. Made sure the skin layer is on the bottom, and the eyes and shading are on the top, but everything should be behind the line layer. Just don't make too many layers...it boosts the size of your pic by a lot!! O_o
When getting to coloring your pic, I usually outline each piece of the layer that I want to color first, and then fill it in. If your lines are thick and dark, this will be pretty easy to accomplish.
Good luck!
