Very simple iPhone app

Hello this is a very simple iPhone app. I run an app business in new Zealand and am looking for key developers to work with on heaps of projects. This app is just a education app teaching people ho to trade forex. I have a complete PDF workbook with source files and and 8 week video course. What I'm after is for people to purchase the app and they will receive access to an clean simple iPhone version of the workbook, some forex basics reference videos and there lesson for that week. Then next week I want them sent week 2 and so on. I want this format this way so they learn better. Ok iPhone app to be simple and intuitive I.e have a home page where ou can go and watch videos or read the manual etc. I want the videos downloaded (some initially with the app) and then each week until the course finishes. As streaming can lag And I want them to sign up when they get the app and login each time they goto the app (so I can capture there email address) This is a very basic app but if you work in a timely manner and have competitive pricing I have a huge amount of ongoing work as my app business is taking off and I need more competent developers Look forward to meeting and working With you
