Custom server maps

hey guys i am new to this forum but not minecraft this post is for people who want to start a server with a custom terrain for spawn and surrondings like custom hills or mabye just tree formations if requested i will make the map you require (the terrain not buldings unless asked to) just post a pic of what your want and post it here and i will try to do it and all i ask in return is credit in spawn and to be able to play on the server
