I'm a screenwriter not an animator so my bid is to write your pilot script, which will include series concept development. Check out my reviews here on freelancer for endorsement of my work.
I have been writing since High School. I've written some stage plays and movies to be competed during an event in school where I won most of the times. I've also collaborated to write in a graphic novel. Once you give me the concept, I'll write the script in an efficient way to have a strong sense in its story.
