Greetings, employer! I'm very interested in this project. I would love to know a bit more about it. So you know, I'm a long time fantasy reader, and a pen and paper rpg player and DM. I drew lots of maps for my campaings, so I understand completely what you need. i would love to create a sketch for you to see what I can do for you, so, if you're interested, contact me on chat and I will create a sample for you!
You can check my work at my Freelancer Profile, I don't have maps there, but it will give you an idea of my skills as an artist.
have a lovely day,
David.
