High Fantasy Map Creation

I am looking for someone to make my D&D campaign world and region maps. I have already created the world map and regions is a free to use generator I would just like some more detailed maps for the website World Anvil. I would like it to be in color with relevant mountains, trees etc. I dont really know what a project like this goes for, so if you feel up to the task please bid so I can get a better idea. I would like to keep it around 100 dollars. I can also give you more information about each region including flora and climate to assist you in creating it.
