All good info. For myself, I probably won't go to the effort of seeking commissions or trying to sell myself to companies. I'm not looking to move into semi-pro status or anything. I'll be much more likely to just post up a PDF document with maps and info laid out on a GM downloads site, and be happy to just get a small fee for it.

But there are probably other artists out there who are interested in geatting paid to make maps.
