I want to create an android phone application for an exciting new mapping application for the mobile phone. It involves overlaying additional content / layers onto google maps (or other map service such as open street map), that allows someone to walk a route. Then then will be able to input data along the route. I will provide a full spec to the developer with the details. I have already made an online example in flash and I have a full design / concept created over a few months. Not worried about what language it is built in as long as it works on both the iphone and android if possible otherwise just android (or just iphone is fine). I am a web developer myself but lack experience in phone development, so I can easily liase with whoever wins the project.
