I need a 3rd party company that does manual mobile (iOS) testing

Our app, Scan, http://scan.me, has over 20 million installs. Since the beginning, we have all of the team run manual tests with release candidates of the app. This is starting to get unwieldy, especially with the varying amount of devices coming out (iPad Mini, are you serious?!).

That being said, we are looking for a third party company that can run a full test suite against our app with all of the supported iOS devices. Anyone know of a team that does this?
