IOS developer for my music app.

Hello! I am seeking a developer to create music education iOS app. Must be familiar in iOS audio and MusicXML. This is a bid for the first milestone of this project. If this milestone is completed well, there will be more work immediately and highly competitive flat rate for the remainder. The requirements are as follows. This is an app that develops sight reading skills for musicians/music students. The student will first select a track (mp3) to play along with. Then, a pre-written MusicXML file (or MIDI if you prefer) will scroll across the screen length-wise and play the sounds indicated. Later down the road, the app will have some other fun social media and gaming elements- but this will not be in version 1.0. For this first milestone, I will provide you with an mp3 and a MusicXML file. Please make the make the MusicXML file scroll across the screen (in landscape), play back the audio indicated and sync to the Mp3 track. That is all. I attached a wireframe of a completed version 1.0 so you have a reference for this milestone. For completion of this project, I need to be able to run it on my iPhone 6 without publishing it to the App Store. Thanks.
