2D Game Art for iPad game

Goal: We need some simple 2D art for a basic top down naval arcade game. Description: The game spec is still in progress, but as a rough idea, please refer to the attached image and the list below for our requirements. Style: We're willing to consider a cartoon style to the sprites, they don't necessarily have to be realistic. As a rough idea, we need the following sprites: - Top down battleship - Tanks (Tank body and turret to be created separately) - 2 separate enemy ships (smaller than the battleship e.g. a cruiser and a speedboat) - Water tiles - 5 different Island graphics (with sand and coast) - Terrain features (i.e. trees, mountains, rocks) - Buildings - Factories, houses - Water splashing from a shell landing in the water (3-5 frames) We have some sprites ourselves which we won't need made for: - explosions - shots - cross hairs If you have a portfolio which includes similar work, we would be keen to see it.
