@kayleenartlover there ate also the storytelling collective challenges. They are affiliated with Drivethrurpg and roll20 and have several writing courses and challenges going on during the year
I will suggest to get the ideas down on paper. Because whenever you ask if someone is interested you are giving a second seat to your own interest, and that is what will make your work a great read, if you want to write it, so start small, put a deadline on and go for it.
We will be here helping the best we can
