Unfortunately, Richard Meredith died at 41 in 1979. I only found a few novels on Amazon. You can read more about him on Wikipedia:
Richard Carlton Meredith (October 21, 1937 – March 8, 1979), was an American writer, illustrator and graphic designer, best known as the author of science fiction short stories and novels including We All Died at Breakaway Station (which David Drake called "Military Science Fiction of the highest order,") and The Timeliner Trilogy.
and here is his bibliography at the Internet Science Fiction Database, which lists Hired Man as originally appearing in If Magazine in 1970.
