Hi Conroy. To answer your question, yes, I have done a few map commissions in the past. However at the moment I am working on a PhD and don't have very much time to devote to my map-making hobby. Thus unfortunately I am not currently able to take on any new commissions at this time. However I wish you all the best in finding a cartographer for you novel.
Thanks for your comment on my Eriond map Conroy.
