I don't mean to suggest anything has to be paid for, just that both writing and map making are creative exercises equally requiring careful thought and skill. If you do not have the time or inclination to became a skilled cartographer, find one, there are many that might do it for name credit only. Random map generators are nice tools to work with, but shouldn't replace a cartographer's skill.
My only point in my previous posts are that both writing and map making are creative exercises and should be treated so.
