Hello there,
No problem to make this app for iOS in a maximum 2-3 days ( I think it will be just one day actually - - IF the API from Wordpress already exists and communication between us it's ok ).
In my CV there are a lot of iOS projects ( over 80 apps, search for "decar studios" on the AppStore - it's my company ). Also, beside this, there are many apps that I've made and I can't show you ( for the educational ministry in Saudi Arabia, an iBooks clone for example ).
Tell me if you would like to get started!
