Android and iPhone developers wanted for new application

We are looking for an experienced iPhone and Android developer to develop several GPS-based applications. The applications will display information for a web-based system, based on the physical location of the app user. They will need to work on the iPhone and iPad, as well as a separate version for Android devices. As we cannot discuss the exact details publicly, please submit a placeholder bid and a few examples of applications you've previously developed. We will discuss the project in more detail over the Private message board, with relevant programmers, after which you can submit a more accurate bid. We look forward to hearing from you. Thank you.
