I would love to be able to do more. I can throw myself at zones to get all the locs you need, take pictures of the textures and all that stuff, supply a tweaked svg file (the site doesn't allow them to be uploaded though but I guess I could put them in a zip file), even calculate the zone erect and other things if needed.
Unfortunately the making it pretty is the difficult part for me, I have the artistic sense and skills of a near dead camel. I will leave that part to the talented people
