I don't know where to get one that mounts to a front hitch. I think a hitch mounted one would be for looks mostly, I wouldn't trust one to stand up to much use.
Unless it is just for looks, you'd be better off getting one that attaches to the frame.
That's what I did, via brackets, and it has held up for years. Of course I don't do much with the bar but it does push open a cattle gate every once in a while. In my avatar you might be able to see it, it's a Dukes of Hazzard style guard. It's been so many years, I don't remember the brand, I think it may be a Westin that I ordered thru a local auto trim shop but without the side wings.
