IPhone App With web service and Web page scraping to display info

We need someone to write an IPhone app. The app will call our Soap based web service to get some information and URL. The app then will do webpage scraping on that URL to get more information. Then it will compose all the information and present to the end user on IPhone. You also need to provide setting for user to configure this app. I think it is a small to medium iPhone app and should take 2 to 3 weeks work. We have a similar product in Android and it took 4 weeks to finish. If this takes you more time to finish, we will issue bonus for the extra time. We need someone with good IPhone experience, good UI design, knowledge in soap based web service call and regular expression in web page scraping. We have the spec and mock UI ready for you to review after we accept your bid.
