New Twitter Background

We would like to redesign our Twitter background to a new design. Design should incorporate our product concept and logo with the intended uses that our program is used for. I am looking for someone with some creativity to be able to design a serious background for our company Twitter page. Design should be fairly universal for standard screen resolutions too. I am not looking for something that will look out of whack with different screen resolutions....we already have that. You will need to submit optional design concepts for approval. Skype capabilities are a must, we only discuss though Skype and do not use emails because it takes too long. If you are awarded the project, you will need to have Skyping capabilities. Payment submitted after delivery.
