Medieval Fantasy Map Illustration

I'm seeking a talented artist to sketch a detailed map for a medieval fantasy world. The map should be neutral and realistic in tone, very much like something out of a Tolkien book.

Key Requirements:
- Cities and towns
- Forests, water, and mountains
- Castles and fortresses

Ideal skills and experience:
- Experience in creating fantasy maps
- Strong understanding of medieval landscapes and architecture
- Attention to detail and ability to create a realistic tone

Please include samples of previous work. Upon request, I can send a simple sketch of what I'd like my map to look like.
