Blackberry wallpaper apps

We are looking to get a blackberry wallpaper app created which will contain 6-8 wallpapers. We want to have an admob banner in it as the app will be free. We want to be able to duplicate the app x 25 so we can release 25 themed wallpaper apps with 6- 8 wallpapers in them. Each app will have a differnt themed front splash page. Each wallpaper app should also have a link to download the other wallpaper apps from blackberry app [login to view URL] apps must be compatible for all blackberry handsets and os. The app should know what handset the user is using to serve up the correct sized wallpaper. We will provide the wallpapers for each app ( you must tell us the formats and sizes you need the wallpapers in your bid) We will privide the themed front splash page for each app (you must tell us the formats and sizes you need the themed splash pages in your bid) You must create the app and user interface to be simple and easy to navigate, maximisingth eopportunity for admob revenue. We have webservice hosting and our own blackberry alliance account on blackerry app world. If you could send a mock up of what one of the wallpaper apps User interface would look like in your bid we will be impressed. We are looking to move very quickly! We have a number of other blackberry app projects with a higher budget and if you do a good jub for us, we will reward you with more apps of a higher budget.
