Hi Ori

I'm currently looking for my first paid commission and would be willing to offer a lower rate as a one-time thing to someone willing to take a chance on a first-time professional, the map you are after also sounds similar to one I have been planning as a piece for my portfolio anyway.
I do only work in physical materials (pen and paper), but a high-quality scan of a physical map may meet your needs.

Here is a link to my portfolio anyway and if your interested send me an email to https://minishcartography.wordpress.com/ and we can discuss some options for a potential map.
