I also wonder if posting in a couple of the state specific forums could work. Might get some more targeted hits.
SC, ME, HI, and FL threads over at:
https://www.backyardchickens.com/forums/where-am-i-where-are-you.26/
They are looking for a photo shoot. Stop telling them to go look at the coops page for ideas. Read their post and not just the title of the thread.
Looks like we thus far have about a 50/50 success rate with reading the original post.
