V V simple iphone ad job

Hi I need to add greystripe ad in a submit page where it will pop up after every time user submit a request to a server successfully. All functyionalities are implemented already and selected coder has to just add this ad in this page. I lwill give the coder the ad and he will ad it. Just it. Shouldn't take more than 10-20 min for a experienced coder who did it before. One more thing. Xcode project is acceptable as deliverable. No need of installer. Happy bidding. As my budget is very much low, low bids are appreciable.
