First off I want to say that I've been following a lot of links on this forum to your various apps and I'm super impressed with the quality of programming and the quality of people on here. Because of the impressive stuff posted here I'm going to throw my hat into the ring and offer my services for any of your audio production needs!
I am a Los Angeles based composer/producer ready to add musical spice and audio goodness to your new app.
My experience ranges from classical/orchestral score to electronic dance and downtempo. My work experience has ranged from lead composer on short films to assisting and support composing for network television (Miami Medical, The Tudors, and Pillars of the Earth.)
My website is being updated as we speak, but feel free to check out
www.nathanielmusic.com for a little idea of who you're dealing with, and
www.soundcloud.com/mister-nathaniel to hear some more recent electronic samples.
I'm sure that I can help you out with music/SFX/sound design that will fit both your schedule and your budget.
hit me up at n(at)nathanielmusic.com if you'd like to talk further!
Keep up the great work!
