So it sounds like you have no real thoughts about trying to sell it commercially although, if somehow someone came along as asked you for your campaign you wouldn't be against it. Not many of us would be. In that case, you can probably just hash out those details with the artist.

Perhaps one of the more experienced cartographers will happen along and pitch in some words of wisdom. We did have quite a lengthy post on transactions a few months ago. I probably should have bookmarked those as I'm sure I'll be looking them up again soon. And don't worry if you need to make changes to your request, it's perfectly fine to do so. That's what this forum is for anyway.
