Crowd Sourcing iPhone App-Map Mashup

Hello Freelancers, In need of an iPhone application to be developed. This application we will need to be able to communicate with a Drupal back end and leverage the phones geo location. Bidders will have experience using the Drupal Services module to integrate with Drupal. In addition, you should have experience with triggering notifications and other events based on entering a geographic radius. The winning bidder may be handed these future integration and feature add projects so please ensure that you are capable or do NOT bid if you do not have experience creating iPhone apps and games that leverage geo location. For now you will only be bidding on the development of the iPhone application alone and may be asked to sign over and provide a full release of source code if we decide to enlist alternate services after the initial project. Bidder should also be prepared to have a long term relationship and provide support when needed. We may also use your services for application upgrades,new features, improvements and so on. Bidder should also be experienced (and be able to provide samples) with location based services on mobile phones, creating map mash ups (with crowd sourced data). Application must also accommodate fairly simple gaming/point system logic that includes tallying totals for specific user activity, preserving scores, and comparing scores with others based on region and membership type. App also must support ability to interface with affiliates in the form of tracking referrals. App also must also support Ad Mob advertising and comply with all Apple Store terms and conditions. Bidder will also have experience creating visually appealing graphics for use with the app. Leveraging existing APIs is acceptable provided they meet the project requirements. Further detail on the requirements of the application will be provided individually to those who bid and place the code word 'iPhoneAppSanDiego' in their bid. You can eventually edit your bid once you have read the project description. Looking forward to your bids and to provide additional details.
