I regrettably do not have much skill when it comes to constructing maps, however, I have some experience creating campaigns. I first need to know what sort of system you are running with. I regret I cannot work with 5th edition D&D or 2nd Edition Pathfinder. However, if you are needing to hire someone for Pathfinder 1e, oWoD (Revised/20th Anniversary) (Mage, Werewolf, Changeling or "zoo" games), Dark Heresy 1e. And have enough lore knowledge to build games set in Faerun, Eberron, Ravenloft (Mostly Barovia, but I can build games that take place in other domains) and even Dragonlance (Autumn Twilight). I've even run/created games using set in Equestria (MLP). Feel free to reach out to me for designing campaigns, co-gming or playing npcs. My discord is TobyFox2002#1527.
