Question about Pixma Pro-100S - 404754

Where can I take the Canon pro 100S to someone who will repair the printer codes for me at a reasonable price? I am very disappointed with Canon Service because they don't care what is wrong with the machine. I have problems with the colours, they are not printed cleanly, i.e. the red colour does not come out. New print head was bought for over 220 Fr. and brought no remedy, always used original ink pack.
