Picture Perfect

I need an iPhone app written for me. We have written it already in Perl and have the code,? but need Mac and iPhone compliance. Ultimately, we want it on iTunes as an iPhone app. ## Deliverables I am trying to get an idea of cost to write an iPhone app. Much of the software is already written in Perl, but much needs to be added as well. What type of? (approximate) cost am I looking at?
