Android Game bug fixes

I currently have a Gameboy Advance Emulator for Android bundled with a Rom of an Old school Space shooter type of game. It uses jni and native library for the emulation. It is on market but has performed poorly due to a few issues. mainly the sound is a little slow and the multi touch controls are a bit flaky. Sometimes it will get stuck going in a certain direction while the user is not touching the screen. I am also told it has issues running on Samsung Galaxy phones. The multi touch issue is an issue in the android code, not the jni. Also I would like to be able to insert adsense ads and need to be sure they don't conflict with the way the game engine renders the screen. Basically the fixes should only take a day or so, But I am so busy with other projects that I have no time to time to work on it. I can provide the Eclipse project, C/jni code ect. .I was thinking one good way to fix the control issue may be to integrate the app with AndEngine. It is an open source Android Game engine with pretty nice Multi touch controls available. I would need to be able to communicate about what fixes were made, so that I may be able to better maintain it. Like I said I can see these fixes taking about a couple days for somebody with the right skill set.
