From memory David worked on Trickochet and Survivosaur, Symphony of Specters did Kaleid, John worked on Retromash and I think others. I may have details wrong, it's been a while since I made games.
I used this site for a corporate video I had to put together. The music/loops aren't free but they have a decent selection and I was happy with the result.
My friend is a composer and has done work for a bunch of movies and games. If you give me your email/Twitter/Skype/whatever, I'll send you his contact info.

These guys have all worked on my own and some of my friends' games too.
