This isn't the place for those type of questions. This is for general information not flight specific questions . Try http://kayak.com
I don't think there are any flights that go directly from Dayton to Richmond but you really need to get in touch with an airline directly for flight information. Delta, United, American, and Allegiant are the airlines that fly out of Dayton.
