Help edit some screens in a IOS app - Development - NO design.

Due to time constraints we need someone to give us a hand with one of our mobile applications. The application is mostly done, we need someone to give us a hand and complete the last few things. We will give you DETAILED specifications to what there is left to do. Most of it is just adding/removing content from a few screens and some back-end work. Most of the screens that need to be edited are only text screens, the other tasks are things like replacing buttons etc. Also needs some backend work like we mentioned above. PLEASE BID ONLY IF YOU CAN START WORK IMMEDIATELY AFTER BEING AWARDED. BID ONLY IF YOU HAVE VAST EXPERIENCE IN IOS APP DEVELOPMENT.
