I'm trying to get an idea of how much professional maps would cost per piece if I retain commercial rights to them. If any artists could email me with their usual rates at email@example.com, I would greatly appreciate it. I'm developing an adventure series, and would like to have maps of a higher quality than I can produce myself.
I would really suggest some more details. People will charge totally different costs based upon a variety of factors, not the least of which is the person's ability, time limit for completion, number of maps requested, etc. Please take a look at the sticky post in this forum as many of those questions will help you get the best artist(s) for your project.
Your request is kind of like walking into a mechanics shop and expecting a single price no matter what's being done to your car....
