2D Artwork required for mobile game

I need someone to help with completing the 2D artworks required in the GUI system of my current mobile game. Although the game is in 3D, the tasks here involve only the 2D works required in menus screens and game HUD. The game is a typical zombie shooting game. Requirement can be seen here: [login to view URL] Some background on the game can be found here: [login to view URL] You can find some info on the menu screens in there.
