iPhone App Updates - Easy for Experienced Developer

Need to make some changes to iphone app. This is a easy project for a experienced iOS developer. We have an app that needs a few updates - iphone to universal - update SDK (RevMob, ChartBoost) - make the menu screen graphics changes - iOS7 updates (adding a few icon sizes) Basically need a working copy, if you are free now and can complete this (should be a few hours to less then a day to complete). Please put in bid. To make this quick, show me some iphone apps you have worked on :) Please only apply if you have time to do this and complete in the next day or two. Also potential for long term relationship and fixing this. Cheers, Mukul
