@ Antonio and lonewrite: How much someone should pay for a map is a thorny question. One of the things that concerns me is that by even suggesting some sort of 'guild approved' rate we will be influencing the prices that people charge and I am not sure if that is a good thing. I think that if you are someone looking to have a map made the best way would be to ask a range of cartographers what they would charge and based on their portfolio, time they can produce etc. make a decision from that.
