ATTENTION ALL GEEK KIDS!!

I need some help. I am writing a series of guided meditation CDs and need background music. The CDs are 30 mins long each and I need relaxing, easily accesible music that includes stuff like Tibetan singing bowls, crystal bells, water, etc.. This would be a 'signature' piece that runs through all the CDs. Any ideas on ways of sourcing such music? Ideally I would like to set up a barter type situation involving internet marketing knowledge. In fact any marketing knowledge that is required. Basically, the CDs will be available online and I could include a link to your site, on mine, and promote your music on my site. This site will have an enormous amount of traffic to it once it is set up (within the next month) Or otherwise free sources. Any ideas anyone?

Please forward to anyone who might be interested.
Thanks.
