Labor Market Survey
You can also conduct a labor market survey to obtain accurate salary information for your geographic area. A labor market survey consists of calling five to ten employers who would hire people for the position you are targeting. Ask them how often they have positions open and the approximate salary range for the job when they do have positions open. By surveying a number of employers you can determine an appropriate salary range for the position for which you are applying.
