I've been creating custom tracks for developers in addition to the free ones that I post daily on my website, soundimage.org.
In keeping with my goal, which is to make good-sounding music available to anyone, I've been trying very hard to keep costs low for indie developers and artists...and so far, most of them have actually been surprised at how affordable custom music can be. If you need something special created for your project, feel free to email me...my email address is at the bottom of my homepage. :)
All the best,
