Where can I ask a real lawyer a question, NOT for "free"?

Are there any reputable sites where I can ask a lawyer a question? I don't mind paying a little bit to get a knowledgeable and thorough response. Searching on Google I just see hundreds of links to "free" sites which I don't trust. I remember seeing websites where you could ask questions to a psychologist or a doctor for, say, $30 and get a good answer. Surely there must exist something similar for lawyers?
