looking for a mapper that would do commissions

i'm looking to set up a trade server and i don't want to be generic and use trade plaza . i would like to pay someone to make a simple trade map with some of my ideas but i don't have a clue how much it would cost or if there's anyone that would do it , so that's why i'm posting this.

if anyone could help it would be greatly appreciated

thanks

im just looking for a simple big spawns and a middle fighting area and a spy crap room
