Where can I find materials for Stringed Instrument Clinics?

[walkhrs]

I am a new clinician that is endorsed by a music store but not a manufacturer. Where can I find educational materials on the internet that I can use for my instore clinics. I specialize in stringed instruments, but not guitar.

I am also lookeing for something like Pyware for stringed instruments. IS there anything?
Thanks
