Compose music for kids game Bus Story

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 bus which gets thrown out to the junkyard because people have all switched to cars and don't need public transport any more. The bus still wants to be useful and tries itself in different roles, fails, and finally escapes to the Green City where people don't have cars and use buses. It's like an interactive book, but the plot alternates with small tasks and mini-games. It's aimed at small kids 3-6 years old, more likely boys than girls. 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.
