Create MIDI music sequance for game -- 2

I am looking for someone who could create a music piece in midi sequence format. 1. I would like to make at the first stage 5 songs. Select one some for the following tempo: One in 50, 60, 70, 80 & 90 BPM 2. For each of the songs, I wand a different beat sound cow bell, triangle...) 3. The beats have to be load 4. Each song should start with 4 pre beats 5. The songs have to be 90 seconds each. 6. I need each one in Midi and WAV. But the WAV has to be the exact timing like the MIDI (probably just convert it but try to make the WAV as small as possible) 7. Each song should be in 2 versions: a. Music plays for about 15 seconds and than disappears b. Music plays for about 30 seconds and than disappears 8. You can select songs from this playlist: [login to view URL]
