Howdy welcome to the guild. You shouldn't have any trouble finding people interested in making some maps for you. I look forward to hearing what exactly you are looking for.
Hi, my name is Jo(h)n and I'm a world builder who isn't terribly wonderful at map design. I'm really joining so I can hopefully find a really great number of artists who will help me realize my dream of being a published module and campaign setting author. I'm looking around for talent now on here and I have seen a lot. I can't wait to have pieces done by some of you for my setting!
Welcome to the Guild thismindofmine! To commission a cartographer you will want to post an add in the "Map Requests" section. Be sure to read the sticky there first however as it will guide you through what should and should not be included in the add.
