I haven't gotten any responses yet, but I did get a couple of re-tweets (thank you to those followers of mine who took the time to pass this on), and I did go out on a limb and I emailed Guillem March directly. The email got bounced back to me.
The awesome Omar Brodrick has tried to reach out to Guillem March and as I was searching around on the internet and stumbled across Guillem March's Art Gallery on ComicArtFans.com and I sent him a message through the site about this. Now the only thing to do is wait and see.
Guillem did get back to me and unfortunately he cannot take any commissions at this time. Bummer. I'll have to find someone else. Let the search begin.
