Paid development: ANDROID plugin to retrieve installed app list and icons

I need an ANDROID plugin to retrieve a C# list of all apps installed on the device in a Unity application. Ideally, the list would provide the following for each app:
- application name
- application package name (in order to be able to launch the app from Unity)
- application icon as a Unity Texture2D object

The plugin needs to work on Android 4+ OS.

Please send me an estimate for such a plugin if you are interested.
