Technical Writing Salary Surveys’

HELP! I’m a new tech writer up for a salary review. I have to provide examples of technical writing job postings – complete with salary offer. I have already searched all local newspapers, and can’t find ONE job with a salary posted. Does anyonehave any reccomendations of where I can go to find such a posting? I’ve also tried monster.com, salary.com, and salarysurvey.com. —Thanks!
