Android UI expert needed to improve UI on current Android project

I have a working Android app which I'm writing, but the UI doesn't look as good as I'd like it to. I need someone with Android UI experience to fix my UI and make it look good. I can give you screenshots of an iPhone app that it is modeled after (what it should look like, although it does not have to be exactly like iPhone, it should fit the Android conventions). There are about 10 screens that all need minor UI improvements. NOTE: Quick turnaround is needed! Preferably if I send you some things to fix, you can work on it that same day. (It should not be very time consuming).
