What should I ask when interviewing a potential advisor ?

1. Who is your typical client?
2. What is your educational and professional background? What certifications do you have?
3. How -- and how much -- do you get paid?
4. Why do you want me as a client? What kind of people do you not want?
5. How often will I hear from you, and what will prompt your calls?
6. Will anyone else be working with me?
7. Can you provide the names of a few clients as references?
8. May I review samples of materials you give your clients?
9. Do you have discretion to act without my approval?
