The mapmaking process, unfortunately, is a tedious one, so usually players don't accept map requests. Your best bet is to:
1. Either find a mapmaker who is selling their mapmaking abilities for coins and pay them it so the map is done.
2. Learn how to make maps on your own.
I recommend the mapmaking discord if you would like to learn how to make a map:https://discord.gg/RPtkck
