Umm, no offense, but it strikes me that you're asking someone to post your fic for you. Admitadly, you said they could make modifications, etc. and it needed some touching up, but essentially it's just posting your chapters and taking partial credit. People like reading fics and writing them, but I don't think that "owning" (if you could call it that) is much covetted.
Again, I mean no offense, I just want to be clear about what you're asking.
