Welcome dLANbandit! I believe you came over from the link I posted at MapTool, assuming I recognized the name? Great to have you here.
Now then to address your request, the first thing we need to know is what applications you have available for mapping in. Also, we'll need to know what sort of style you would like to use. Maybe a link or post of an existing map that you would like to emulate? Also, are you only looking for the arena and none of the surroundings?
Finally, it just so happens that this weekend we are updating the site so there may be some delays in getting replies until things are up and running full speed again.
