Audio Matrix Circuit controlled by Arduino

I want someone to help me complete a circuit design I have been prototyping.

I have built a very simple circuit for switching audio devices based on the TEA6420 audio switching IC and 4 preamp IC's (TDA7449) - controlled by I2C bus from an Arduino. I have conceptually already built the circuit but am looking at someone with electronics experience (I am just a weekend hobbyist) to help me design a proper PCB I can get printed that has good design and noise isolation etc. If I can find someone who also has C experience to help with software that would be great. Again, I have built basic app but it could be a LOT better built by someone with embedded experience.
