Compose music for an educational kids game

We are a small team developing kids apps. We need an music composer to make four 1-minute long music tracks for an educational game for iPad and Android. The game is about a small alien getting lost on Earth, meeting with human kids; they then build a UFO together and he flies back home. It's like an interactive book, but the plot alternates with small tasks and mini-games. The tracks should be in raw WAV format, no compression, looping (gapless) and approx. 1 minute long. 1. main track - will be played on the starting screen and while the player is browsing menus, selects the mini-games to play 2. story track - is played while the player plays through the story and solves simpler tasks inside the game 3. mini-game track 1 - is played while tasks are solved and mini-games are played, and these tasks are logic ones (sudoku, maze). This should be a more relaxing and thoughtful track 4. mini-game track 2 - same as 1, but for tasks requiring reaction, memory etc (not logic). Should be more cheerful.
