I need a graphic artist with experience in mobile UI to take some sketches I have made and create credible wireframes for the development team to work from. This is for a 3D iPhone game being developed in Unity. There are about 14 screens - they need buttons, icons, characters, environments displayed clearly in the wireframe screens. None of this is final art - just clear frames for the programmers to work from. Having experience in 3D game UI for ideas on placement, display, and offering suggestions to improve the UI is an advantage.
