Basic Facebook Application

If you already developed a facebook app in the past or currently owns one, this is for you. All I need is a basic app, can be gifts, dating, which XYZ are you? or any other type of application, I need it fast because I need to run tests on that application, so you will just need to install it my [login to view URL] server and get paid. It can also be an application that is currently running and that you want to sell. I welcome any suggestions. Thanks.
