RPG Campaign Map Remake

[Alsaindar]

Hello everyone, I have a campaign that I run in a custom world, and that I intend to use well into the future. I have a very crude map I made myself cutting and adding onto as needed over time, but I would like to have it remade by someone a tad more talented, with some additions. The Auriga attachment is the current map of my world, with the middle earth attachment being roughly the type of detail and coloring I'd like. Rough rundown of what I am looking for, is a much cleaner rendition, with the shorelines cleared up, more terrain distinction, some islands added/fleshed out, and I would like the map mirrored horizontally (so that the map is copied and flipped to create a mirrored northern and southern hemispheres).
