What is the average salary for an administrative assistant in an interior design company? - interior design companies

I work in a firm of interior design, and I wonder what is the average salary an entry-level model, an administrative assistant in a fixed facility.
In a two-week study and after two weeks I will have to study the salary issue, how can I contact? Are there any guidelines? What is the professional way to approach the topic?
