Just in case the developer below was unable to come up with what you needed, I suggest submitting your app idea to the www.AppReque.st website. It's a free, public database of as-yet-produced app ideas. Maybe you had intended to make some money with this app idea. If that's the case then I wish you lots of luck. If, however, you just want to have the app produced so you can actually use it, then AppRequest may be your best bet. They're adding new app ideas daily and it's a very friendly community.
