Android programmer needed, for UI tweaking, and other tasks

I am developing an Android application, so some code is already written, but the UI needs improvement to look like it should look. Also some code needs to be added for small things, but most of the classes are in place already. Looking for experienced Android developer/coder who will work for a reasonable hourly rate. Please mention what experience you have. I can send you pictures of the UI that needs to be developed, and will send the code once the project starts.
