Android Application using GPS

Using the GPS in the Android device it should determine the location and select an area with in a radius of X (changeable in app set up) number of miles. I am looking for an application that can connect upto to a website. Website is php/mysql, and it will need to get locations from a database and display them on a map on the Android device. Locations will have latitude / longitude values. Then if you tap on one of the locations on the map (which is on the Android device) it will display a window with more business name, address, phone and description if one of the fields in the file says to. There may also be additional information that would need to be displayed on a full size window. The website is not part of this project. The project is for basically 2 screens and a couple windows that popup off the screens. Popup windows will be the same regardless of which screen you start from. If you have any questions please contact me. I would prefer someone who can speak English fairly well because I will want you to explain the application to me upon completion. **This is phase 1 of the project so there is a possibility for more work if this project goes well.** I may also want to do this for iphone. I want to deal directly with the developer, not a company representative. If the project ends up being more work and you can explain to me why, or the requirements change I am open to negotiating additional pay. I would like this delivered in a week.
