How would you go about selecting a Certified Financial Planner?

My wife and I are financially successful adults, but we need guidance with the next steps, including:

• Private equity co-investment
• College savings for children with special needs who may or may not attend university
• Retirement savings beyond the standard 401k and IRA options
• The tax ramifications of all of the above

My friends are generally not at this level of planning needs, so those who have worked with a CFP have had only much more basic questions. We have known plenty of financial advisers over the years who just give bad advice or canned advice. I expect our needs will become more complex over the next decade.

How do we find a quality CFP who can help with the above? What is a reasonable price to pay for this help?

Thank you for taking the time to share your thoughts!
