Iphone APP development

Looking for a competent programmer to work with me in creating my iphone app, the developer would need to sign a NDA before undertaking the work. The App will be fairly basic, where a user can browse categories and view a few small pictures of the item, and a small description of the item they are viewing ( I will provide a breakdown of categories I want along with all the content pictures and fact file) I would also like the ability for a user to take a 10 question quiz about their item asking certain questions about the item they have but want to identify and then it will shortlist the categories that match ( I will work heavily on this with the winning developer) I would like to develop 2 versions of the app, Paid version One that will be paid for and will have 1000 items and no adds, Free version Less items (not decided how many yet) and adds will be placed promoting the paid version etc. There are a few other features I would be very interested in working on but I want to get the base app designed and working first. -My requirements are that the programmer is able to work to apples standard of code that will be accepted to the app store. -Must speak english and give me regular updates and check with me on any questions work with me to create the perfect app. Any questions please message me.
