need a very simple game

Hello, would you be able to help me in creating a very simple gba game? I mean very simple, only a few lines of code. And I need this asap, if I were to give you less than 48 hours, what would your quote be? All i need in my game is a person(sprite) that can move left and right, and from the top screen there will be falling rocks, if the person gets hit he loses one life. That is all there is to it, no levels, no additional stuff, just those features I have some code that I would like to base my game on, maybe if I give you this you can change it around? It has exactly the same mechanics and controls. It is a tank game from loirak web. Maybe you can change the sprites/background and keep the same controls? Again I must iterate that it must be a simple GBA game with the simplest C++. I know it is a very short deadline but 2 other experts have not done their job properly and has left me in a situation So, can you help me out? look forward to a reply :) I will need the source code and the gba file. I use programmer's notepad 2 for compiling. How much would you want my friend? Again I must iterate I dont want wanything complicated
