Chief of Staff - Business / HR Research - repost

I am looking for a native Brazilian to do some research on a position in business. I am looking for research into how the "Chief of Staff" position is utilized in Brazil. Specifically how it is used in the business world. The first step would be to look at job postings for the "chief of staff" in industries (NOT government, military, or medical positions). I need the following information: What the position is called. What company is posting the job. What industry the company is in. Expected Salary Range. The Duties/Responsibilities associated with the job. The qualifications associated with the job. The preferred education level for the job. The preferred prior experience level for the job. I would like 10 job postings worth of this information, saved in word or excel. Additionally I would like them to be spread across multiple companies/industries. I would also want an overall search of the position in Brazil. I would like statistics on salary, years of experience, industries that utilize a Chief of Staff, gender split (male/female), average age, schools/degrees that Chiefs of staff attend/hold, and any other pertinent information.
