Well, first: knowing where you are and/or how far you are willing to travel, as well as what you wish to learn (sword fighting is a rather broad subject), will allow us to be more helpful.
If you come out to Oregon City, there's an academy here that specializes in the Scottish Broadsword.
You might check over at Sword Forum, in the Swordsmanship Community section, to see if anyone has posted about opportunities in your area.
You might also contact your local fencing school or association for leads.
Lastly, I offer this: Classical Fencing and Historic Swordsmanship Resources.
