Small update for iPhone app

I need an update for my iPhone app - Scan&Shop: [login to view URL] In iOS4, apple changed an API to use for barcode scanning algorithm, therefore my 3rd party providedr (redlaser - [login to view URL]) changed their library accordingly. Now I need to change my app to accommodate this change. I have clear instructions from RedLaser how to change the code - should be very simple and quick change. I also have new library to compile a code with. I estimate one week time frame to complete this development and expect the developer to confirm or challenge this time frame when he will be familiar with all instructions. I will provide current app code and 3rd party library. The deliverable should include updated code.
