Android development

Hi all, I need someone to build me an app for android using eclipse. the app I need to build is VERY basic, a normal developer would do it in one day. So the specifications of this app need to be: -A very basic music player(very basic, only play, next , previous buttons,a button to select songs from a playlist sd card). -and it needs to use the built in hardware sensors to do something. In my case I need to use accelerometer or gyroscope (I think) to whenever the song is playing and the user is holding the device normally the song plays normal, if the user turns the device to the left the song will play slowly and if the user turns the device to the right it will play the song really fast. Obviously this needs to use the sensors. As I said this is a very basic app, the only reason I can't do it is because I'm new to it. So can you please help me with this? My budget for this is 150$ to 200$ ..
