I wish you good luck, Nicole (or should that be 'lotsa luck'?), but I think you might be asking for a lot.
Speaking as someone who edited parts of a story for a non-native-English speaker, coauthoring would be an even bigger job. And for a story that's already over 200k...I think you're asking for the moon, here.
Oh, and if whipit volunteers, just close your eyes and walk away.
(Actually, Powerone has coauthored with several female authors. You might try PMing him.)
