Also not to be a further damper on your goal here, but [Unpaid] Cartography Requests are usually for non-commercial/personal projects - maps for home games, situations where the recipient of the map has no intentions of earning money from it'souse. Your request is for a commercial project, thus are unlikely to find volunteers to give you a map, only for a published mention. You're probably going to have to pay something, even if some reasonable amount like $50 or more. I hope you have luck finding someone, though your chances are small.
