Mobile graphics designer

Project Description:
Looking for a graphic designer that can make me the following;

1 professional Android application logo / icon
10-15 icon images (for buttons / markers / etc)
2-3 background images

If you have worked with mobile or have mobile-like samples, please share.

Here is an application that I currently have ; https://play.google.com/store/apps/details?id=com.RDJLdev.wordhelper

I would like images / icon / etc to be more professional than those in the link.

Thanks!
