I would like to hire a Mobile Developer

I need a real time basketball stats tracker app (for Android) that handle with data, like the list of the players of teams or the team name, retreived from a web services. In my idea, the user have to: use his credential to login download a list of possible players for the match compose the teams using the list of players record the stats: during the match he will see an image of the basketball field in the middle of the screen with alongside the lists of players. On the top a section with a button for all the possibles actions and a timer. The user should have to select the player, the action, and the point of the field where it happens and the app should record every entry. At the end of the match, the user ask for a sign (with a pen or the finger or something else) from the two coach and could see a complete list of the events (to modify potential errors) and confirmating the data send all to the server (the action lists and the images for the signs).
