I have a Canon EF 24-105mm L IS USM lens that appears to need a new aperture cable. I cannot seem to get  a contact  number/email to request an estimate. Can someone kindly help me. Thank you.

Recently the main dial on my Canon 6D seems tighter & does not move as easily. Considering the age of the camera, I suspect that it could use a thorough disassembly & cleaning. I prefer to have this done professionally by either Canon or their author...
