Typical contractor rates are in the $75-$150 range. Other than that, it really depends on your app. Here are some common considerations:
If you can nail down some of those questions, it will give us a better idea of how to answer your question. For orders of magnitude, think of it this way: App development is a game of tens of thousands, not hundreds. Very basic apps will cost north of $1000 easily, and something as complicated as the app you link to can cost >$75,000 very easily (check out this link for the example of what it cost to develop Twitterific)
