Clean up plus additions to an iPhone/iPad application

We have a project that we are working on at the moment. Our iOS programmer is away but we need some work completed before his return. We need a few edits to an existing app to be completed. Just a slight edit to one piece of code and a custom tab bar with raised centre button to be added. Probably 5 mins work for a skilled programmer. It is a tab application and on the first tab there is a collection view with images on that doesn't always page properly when the app is opened on that tab but if leaving it and returning to it, it works fine. I am also looking to replace the logo tab with a raised version of the logo on both apps and would also like the orientation issues sorted for the images if possible. I would also like a share function for the images. There may be more work available if happy with the price and job done
