Iphone app - recruitment business

I have a simple Iphone app which connects to my recruitment website allowing the user to search for jobs on the database, and to submit an application by email. JASON already installed on the Joomla website and the app generally works as it should. The project is 90% done however the current developer does not have time to finish the work. I need someone reliable to finish the work. Mainly to clean up the screen design (use same fonts on all screens etc) to ensure that the design is the same on all program screens. The changes are very small and you should be able to finish them in a couple of hours. Fixed budget 150 USD. Deliverables: App and full source code.
