Are you asking about how much time it will take to collaborate with a comic artist? There's no way for anyone but you who could even give an estimate on how long it would take to write the script, finish your story, etc. Some people can write really fast, and be done with a story in a couple months. Others, years. Some will get halfway through, think up better things, then undo all their work because they find it's worth it to start over again.
Or are you asking about how long it would take to find a comic artist? How long would it take for them to draw out the story? Or if this will affect your studies (which would be up to you, so no one else would know)? I'm not quite clear on what the question is ^^
