Agent's fee is negotiable so I would suggest that you pick up the phone and call a couple realtors and ask them your question. I just have to make a comment about a few hours of work. Even if you have found your buyer the work isn't going to be a few hours. There's a lot more to it behind the scene to ensure a smooth transaction in real estate. I would suggest that you ask the agents that you are interviewing what else do they do after you have found the buyer.
