Welcome to the forum...
Sounds like you have a good framework for a story, and the best person to write it is YOU.
Can I suggest that you write the first chapter and post it, while soliciting responses from readers. You may be surprised at your own capabilities as a writer, as there is nothing mystical about this craft. Read through some other stories on this site and you'll soon start to feel you can do better than many of them
I look forward to seeing your work on the site soon.
Best wishes and regards
Marcus
