How should I prepare for a first meeting with an attorney?

[Lee Syndergaard]

I'm soon meeting with an attorney who, according to the person who referred me to him, is well versed in real estate investing. As I've never yet had such a meeting:

How do I make the best use of our time? 

What should I come prepared with (business plan; list of questions; goals; etc.). 

What questions should I ask? 

What questions should I be prepared to answer? 

On a related note, for budget planning purposes, what do you pay your attorney?

I'm in the Minneapolis/St. Paul area, FYI.

Thank you!!!
