I might be interested. I have a background in GIS and know how to make maps that actually reflect spherical geometry, so that you really could put it on a globe and it's wouldn't look distorted. You can see examples of my work here: http://draconic.ca/portfolio/ http://www.cartographersguild.com/album.php?&u=9958

This sounds a lot like it could be quite open ended an involve a lot of back and forth and adaptation to make it work on a globe, and that, especially combined with the desire for copyright means I'd want to do it on an hourly rate basis with payment as it progresses. Any fixed quote I gave would be a complete guess that would probably bite one of us in the ass. It also means if you decide you want to take what's been done and stop or switch to someone else to finish it, that's fine and I'd provide all the source and intermediate data.

Also, simply zooming in on a map doesn't really work. This has to do with the problems of the globe being, well, a globe, and a map being flat. Different maps need different projections based on their extents and purposes. If you specifically need "zoomability" at the cost of a number of having other problems, the normal Mercator projection can work, as in web mapping applications. But it really isn't a good projection for final, static maps except for those used in a particular form of early marine navigation and a few other special cases, and it's not at all appropriate for large scale (Zoomed in) maps. If you want larger scale maps to look right, you have to essentially redraw them in a more appropriate projection. Details and symbolization also need to change as you change scale which likewise requires redrawing. Using a GIS can help somewhat with this.
