I'm afraid I really can't commit to something like that, sorry. I know I'm not moderator here any more, thus I do have some more free time to post around and whatnot, but I'm still kept ridiculously busy with college work, and I have to focus on that.
You can feel free to say what kind of music you're looking for and maybe if I have enough free time at some point I could throw some together for you (depending on whether it's MIDI transcription of songs or completely original music - the former being preferable). I'd suggest asking around for other composers as well though, as I've left a fair few people disappointed/empty handed in the past, due to time constraints. :(
