Hello,
Provided this is a manga or video game style character design, I should be able to get you either a digital .bmp of 4 directions, or a colored pencil sketch of 4 directions, as well as give assistance in a back ground story if you do not have one yet. All this can be completed within 3 days of giving me the instructions and necessary materials (you already have the basic idea/concept sketch down, if I am not mistaken...). You will probably receive it much quicker than that, but I believe in putting a buffer day on for in case of emergency reasons. I hope to get to work with you, it sounds like a fun project!
Sincerely,
Sasha Styles
