Simple Game Project

I'll be needing a simple Battleship game in C#. The game must be playable on a custom-built grid based on the user's input on how large they'd like the grid. I'd like for the game to run in a console application without a GUI; a GUI will come later. The rules of battleship, will, of course, follow the basic Battleship rules. This project shouldn't take very long to complete. If it is finished expeditiously and correctly, I do not mind throwing in a bonus.
