Do a search for a guy named turtlepimp here on fauna. I think his real name is Andy Surry. Not even sure if he is a member here anymore, but he had a large selection of turtles and might either have them available or know where you could readily obtain some.
In the future, use the resources of the board to your full advantage. Don't be shy to seek out a reputable member and ask him or her to refer you over to a reliable source. Thats what were all here for....to help each other.
Good Luck finding some....
