Greetings. My name is Jeremy Trammell and I represent a group of developers and designers in Portland, Oregon, in the U.S. We have extensive experience creating Android applications and would be happy to assist you with your project. In fact, if you review our recent projects on this website you will see that we have just completed an Android live wallpaper which renders a real-time 3d fabric simulation modeling the Pakistani flag. One comment I have regarding your specification document is that there should be no need for you to go into the software to change the size of the images drawn. I would recommend that we have the software automatically select a reasonable size based on the screen size and layout. Other then that your specification makes perfect sense and we are ready to begin immediately.
