The 42-year-old woman was severely beaten when she was found by a passing bicyclist on July 29. No arrests have been made.
Paulding County sheriff's Cpl. Ashley Henson tells WSB Radio that authorities hope a reward will prompt a response from someone who knows something about the attack.
Henson says the woman is still in a great deal of pain and hasn't been able to give detectives many clues about a suspect, other than describing him as a white male with dark hair.
The reward fund has been established at the Bank of North Georgia in Hiram.
