Hello,
I'm a published writer (two plays, two short stories). As I haven't written much of late, the prospect of expanding your story into a novella format is a very attractive one.
I'd be willing to ghostwrite for this - though I would just as soon take a contributing author credit, and release all rights on the work to you (I can provide a written contract for that if desired).
One of my published short stories (this one was flash fiction really) appeared in a lgbt-themed magazine. It doesn't have any good dialogue examples, but if you'd like to see some of that, I can provide some play transcripts.
I believe I can upload the content to my profile - I'll do so now.
Thank you for your time and attention - I welcome further discussion and any questions you might have,
--TS
