Need help with story ideas for HIE and displaced stories. And possible co-author help

So I'm fairly new to the fandom, and I wouldn't consider myself a brony but it could be debated. Anyway I require assistance for some ideas for an HiE or displaced story. I mean I have one idea but have no idea how to go about writing it. Also I work better with someone else so if anyone is interested in being a co-author let me know, I would love the help. Thanks for stopping by.
