Where can I 提出する a new comic または sell a comic I created so the media/animators can use for their own production?

i don`t really know if this would work but あなた could call up a comic book store and ask them if that doesn`t work maybe あなた could make your own website and then put it on there または type it on there and then see if anybody likes it.

What I would do is look into a bunch of different comic book industries and go on their websites and see if they accept unsolisited proposals
