Get a fight choreographer who has training!  Fights, no matter how simple they may seem in your head, can be very dangerous.  Especially with the weapons you've described!

If you can find one, try to get a fight choreographer who will make a character-driven fight, as they're often more interesting to watch.  If you go through a play with fight scenes (esp. a lot btw. different characters), you'll see that each character has a different goal in fighting, whether it be to show off his skill with a weapon, frighten  someone to simply go away, or actually harm someone, etc.  Good fight choreographers incorporate these elements into their fights.

I will chime in with a third "Get a fight choreographer who has training" and practice, practice, practice! Even the simplest fight scenes can go very,very wrong when adrenelin is high. After months of working with a fight choreographer I had a friend in college who was suppose to be tossed off stage on to a mat. Simple. Right? The show was going really well. Everything was high energy. That was when she sailed past the mat, and hit the wall.
