You mentioned you use your bosses guitar.. Have you asked if he will part with it..
You can also try GraigsList.. You can select by the state you live in and select an even closer area by city... One person I found in my area had several guitars claiming he was down sizing his collection. Another had two guitars that in need of overhauling.. Another had one claimed to be brand new.
Don't forget your local newspaper classified and pawn shops. Music store may have trade-ins. And the music chain store will have returns and blems.
good luck
