Interesting world you've got there. Are you looking for someone to draw a new map based on the one you have, or just add textures to it? The thread title suggests the latter, but if you want it to be in the style of the Essos map you linked, it'll probably require the former. Also, I'm sorry if I'm misunderstanding here, but the payment you are offering, is it to come up with place names? I might be interested in taking this commission depending on the answers to those questions
