Android Live WallPaper

I am looking for an Android Live Wallpaper that will run on Android 2.33+. The requirements, and what I am looking for from a developer are as follows: 1 - The wallpaper will feature 5 sets of images, with each set having 12 images in it. I need the Live Wallpaper app to have a Preferences screen, which would allow the user to select the set that they want to use. This can be done with a Spinner control (I can improve the looks of this later). 2 - Once a set is selected, each image in the set will rotate into view at a certain time of the day. For example, at 12pm, the wallpaper should display [login to view URL], at 2pm, [login to view URL], etc. Images will rotate once every two hours or so, but again, we will show a specific image, depending on what time it is. For the sake of development, assume that you have 12 images, displaying a different one every 2 hours. I need the live wallpaper to be compatible with most resolutions and screen sizes, so I will be looking to the selected developer to recommend the exact sizes I need to supply the artwork in for HDPI, MDPI, and LDPI screens. The images should scale and fit each screen nicely in landscape and portrait mode. Again, I'll supply the art based on feedback from selected developer. In landscape mode, the bottom half of the images will be important to see. I am an Android developer, but just don't have time to put this together at the moment. You can outline any challenges / problems you see with the above description in technical terms. With that said, I also know that this is not a difficult project, with the most complex task being the scaling of images as necessary. As such, I would expect this to be wrapped up fairly quickly and on a low budget. Thank you for looking, Alex
