I need a cheap one way ticket from Rio-Brazil to Atlanta-GA, any good travel agencies from the USA?

I have a green card and I'm in Brazil for 2 months and I'm going back to the U.S. this November. I wonder if there's a good travel agency with cheap/affordable airline tickets, but I need: Rio de Janeiro-Brazil to Atlanta-GA. I also have 3 small dogs I need to take back with me. Any help is appreciated.
