Android Tablet User Experience Design

I have an immediate need for a mobile UX designer that can help translate some low-fidelity wireframes to some visual comps for an Android tablet app. The immediate need is pretty targeted, helping to set visual direction (not necessarily brand concept, graphics, etc), so I’m looking to time box the effort. I would imagine 3-4 screens. I will be able to provide you with a logo and some direction on color palete. I'm looking for someone with Android UX / UI experienece. PLEASE, this is a design role not development so only respond if you have Android Tablet UX experience. Once we get through the first phase, there may be additional cycles on screens, graphics, etc I would expect to receive the .psd files and high resolution .png visual mockups as deliverables
