CAMWorks post processor for 4-axis machine

I am searching for a specialist who can help me with post-processor updates to work with for a 4-axis machine. I have a proper post-processor that generates code only for the 3-axis. So your job is to modify it to work with rotation head axis A(360 degrees)
