phone game app android & iphone

I need a game built. I will supply all graphics in png. Can supply sounds also for the game. It is a free downlaod, basic 2D game space invaders style shooting game see attached image. It is a battle the clock style game, rolling screen during stage, and than face a boss if beat time for stage. Really easy concept. No tricky features, just a start playing style game. High scores (top 10) are kept online so they can be linked so everyone competes for the highest score. It is a free download, so I need it put together and uploaded to both iphone and android stores. Just encase there was any potential money accumulated from downloads, I need the to make sure the person who makes this game does it all correct encase for some weird reason the game ever went viral and made some money. I have herd stories about peoples games going viral and it wasn't made properly and they didn't make a sent when they should off. See example game pics attached I made to show my game concept. Let me know what you think about the ability to do this project.
