It is pretty hard for anyone to agree to work with you when you give no details out.
Are you looking for a coauthor? Are you looking for someone to check your scripting? Are you looking for someone to edit for you? Are you looking for someone to give you ideas? Are you looking for someone to playtest things?
You have no details in this post about the "storybook" that you want to make.
This is not likely to get responses from people that will actually help you. The people that will agree will likely be newer people, weaker writers, or/and people possibly looking to get some credit for little to no work.
If you want people who will make an effort to help you, then you have to put some effort into your request. Give us some details. Give us a clue to what we would be agreeing to do.
