Material for Jon boat decking?

In the planning stages of decking a 14.5ft Lowe aluminum boat. I would like to make the decking out of aluminum. Does anyone have a source for this material in the Louisville area? How much is this stuff going to set this poor fisherman back? Any tips on venders, material, construction, etc... greatly appreciated!

Birdstrike,
I do this kind of work. I usually work on boats that are a bit bigger, but a jon boat should be no problem. I live in Louisville and can put you on the right track.
