iPhone/Android/Blackberry app with Ruby on Rails work

We need to have an app for iphone, blackberry and android. The app will connect to a website that is running on ruby on rails to retrieve and display data. It should also maintain a local cache. The website maintains a calendar of webcast events. The app will allow users to search through a list of audio events and play the event including live events. The backend server will be running wowza media server that will provide the appropriate live stream. There will also be a calendar screen with a list of these events and their scheduled time. The user should be able to set alerts for the different events from the calendar or add these events to his phones calendar. There will also be another screen that will allow the user to modify his settings on the website/app. Also, the app will include a subscriptions feature for the user to subscribe to the various data that he is using on the app on a monthly basis. Certain data such as live event streaming will only be available to paying users. The selected programmer would need to be familiar/capable with Ruby on Rails, linux environment, iphone, blackberry and android development. I would prefer one team to handle the entire project rather than split between iphone and other platforms. For those who bid, please provide further info about your specific capabilities. The timeline of this project is very important and after award it has to be completed within 3 weeks. Please bid for whatever platform you can develop the app for.. with your proposal, suggestions, quote and time frame. Regards, PB.
