Try a local surveyor/ engineering outfit. Where I work they have a large plotter that can do all sorts of things. I have made may copies of maps at different sizes to keep in the boat and in my truck. They may charge a couple bucks but I would imagine it would be cheaper that a staples or kinkos.
I have those, what I am looking for is something for my wall that is maybe half topo half photo. mytopo.com has these kind of hybrid maps and I want to hang it between a couple of fish mounts.
I see a few of my honey holes on those maps...
I fish a rock ledge on ky lake and have a great hump on barkley.. I might try to fish them in june
