Don't want to be rude but pay a designer or make your own logo... Is my experience here, when I requested help for a WorldPainter map (a large one, 20K) I knew that anybody would help me, because is not other people business...
One of the best things of Minecraft is the freedom, but everyones say that. For me, I'll add that this game is great because we can play with other people from another country without problems, the lag is no so important here.
