What is a fair price for an INITIAL patent attorney consultation?

I have the relevant prior art records and have simple questions that I need answers to before I can determine if my idea is feasible. If those questions are answered to my satisfaction, I would be interested in taking it from there. I really just need to sit down for a hour or two to ask a few key questions. What do attorneys generally charge for a simple, one-time (for now…) visit? I know many people have made this first where to buy prescription drugs without prescription step so I just want to be prepared…
