Work on UICollectionView

Hi, Attached to this project is a sample iPad Project, in it you will find one screen that hosts a uicollectionview, I already preloaded that with some local images. I also added UILongPressGestureRecognizer, which will activate if the user presses long enough on any cell. I want to add the ability to delete cells. I need someone to go in and work on the uicollectionview cell, when the long press happens, and in the project you reach -(void)startAnimatingCells:(UILongPressGestureRecognizer *)gestureRecognizer method, I want to shrink all the images in the collectionview by 40%, and then start wiggling or wobbling them ( same way an iphone home screen moves when you want to delete an icon), also add a small delete button ( with an X in it) on the top left corner of all moving cells. When the user clicks on that delete button, delete that cell, and all remaining cells should return to original size and stop wobbling. I need this asap, before contacting me make sure you have finished the work and made the changes and attach them as a zip file to your message.
