I'm looking for a literary agent

I've written two politically-conservative non-fiction books. I'm looking for a literary agent who will submit my books to publishers like Regnery and HarperCollins who publish politically-conservative books. I offer a set fee plus higher-than-usual agent commission if you sell the book(s). I'm also looking for a literary agent who handles screenwriters and feature-film screenplays. I've written an exciting screenplay, "The Revolutionist" that is an adaption of the best-selling novel, "Scaramouche".
