iPhone App for classifieds site

I’m working in a new classifieds site using OxyClassifieds ([login to view URL]). This script is PHP and MySQL (Although the classes are encrypted with ioncube). I’m looking for the iPhone app (native) to my site like the one for a Spain site [login to view URL] [login to view URL] same features, post with photo, search capabilities, etc. Developer has to develop the API, JSON or whatever things the app needs to get and post to the database. I can provide the script for test environment. I will review bids across the 60 days of this post before select. Please send a portfolio or demos. (Spanish language is a plus) Please Ask for more details if needed before bid.
