Hey, if you still need help, I'm quite good at editing, as in grammar and writing and all that (if I dare say so myself).
I don't know if you already have someone who does that, but I'm volunteering.
I'm not very good at writing myself, as I've never written any story before, but I can pick out mistakes and flaws in other people's works very easily. (does that tell something about me? lol)
So, let me know if you can use my help
