It's a bit different when it comes to business travel. I'd use and pay for travel planning for business where my schedule can take me to out of the way places and the schedule can change frequently. There is a tier of business traveler in small businesses or who are self employed and need an economical itinerary with specific attributes for flights and hotels, but who don't want to stay in crappy places. I've spent far more time on HipMunk and on the phone with hotels.com and re-booking flights than I should have to. Maybe start a manual service, learn how this stuff works and then automate it.
