I am an Argentine of 29 years and have worked in the comic industry since 2010.
I know and use various techniques of color, from digital to traditional.
My work has been published in publishers like Dark Horse, DC Comics and Blue Water Productions.
If the pencils or inks that you want to color are very complex'm afraid I'll have to raise my offer up to 30 USD, but if your pages are not very complex then I can do it for 20 USD page.
Feel free to inquire for any questions.
Thanks for your consideration.
