You could probably find a Kendo instructor somewhere in your area. Tai Chi also has a sword form if you're looking for something more meditative. Medieval groups can also be helpful if you want to try more of a free-form style. They also have the added benefit of letting you play with their stuff for free. A word of caution about medieval groups though; you can have a high rank and be a really crappy teacher. There's no skills test to determine if you can teach or if your technique is safe for others to study. You'll need to watch people fight, find someone who has a style you think would work for you, and then ask that person if they'd be willing to teach you. I'm not trying to discourage anyone from going this route; I fight with a Medieval group and I have a wonderful instructor. There are good martial artists in Medieval groups, but there are also a lot of people who will teach you things that will wreck your elbow and destroy your knees.
